What is an Turbine Flow Meter?

Turbine flow meters are used in many industries to measure liquids, gases, and vapors reliably. By using the mechanical energy of the liquid (or gas) to move a rotor in the flow stream, they are able to calculate the speed directly proportional to the velocity of the fluid. These flow meters are designed to accurately measure the flow of gases and liquids through pipes. This is done on a volumetric basis. Using a turbine flow meter requires applications of clear fluids that range from sub-atmospheric to 6000psi. Temperature ranges should remain between -450 and 6000 degrees Fahrenheit.

Advantages of Turbine Flow Meter

High accuracy

Turbine flow meters typically provide highly accurate flow measurements and are suitable for applications requiring high accuracy, such as industrial process control and scientific experiments.

Fast response time

They have a fast response time to quickly capture and react to changes in flow rate, suitable for applications requiring real-time monitoring.

Wide range of applications

Turbine flow meters are suitable for a wide range of flow rates, from low to high flow rates, and therefore provide reliable measurements in a variety of applications.

Corrosion resistance

They can be used to measure a wide range of liquids and gases with good corrosion resistance, suitable for applications dealing with corrosive media.

No direct contact with the fluid

Turbine flow meters do not require direct contact with the fluid, which helps to minimize the impact on the nature of the fluid, especially for applications where contamination needs to be avoided.

What Does a Turbine Flow Meter Consist of?

Turbine blade
One of the core components of the turbine flow meter, the turbine blade is a set of rotating blades usually fixed on the shaft, installed in the channel through which the fluid flows. When the fluid passes through the channel, the turbine blades will be subjected to kinetic energy and rotate. The number and shape of the turbine blades may vary depending on the design of the meter.

Shaft
The turbine blades are attached to a shaft, which is responsible for transmitting the rotational motion of the turbine blades to the sensor for measurement.

Sensors
The sensors built into the turbine flow meter are usually magnetic or photoelectric sensors that detect the rotation of the turbine blades. These sensors sense where the turbine blades are passing over them and generate an electrical signal.

Signal processor
The signals generated by the sensors are transmitted to the turbine flow meter’s signal processor. The signal processor records the rotational frequency of the turbine blades, usually in the form of a number of pulses or a voltage signal.

Display or output interface
Turbine flow meters are usually equipped with a display or digital output interface for displaying flow rate and flow data, or for transmitting data to an external monitoring system.

Housing and connections
Turbine flow meters are typically installed in a pipe or fluid path and have an external protective housing and connections to ensure fluid flow through the turbine blades and to protect the internal components.

How Do Turbine Flow Meters Work?

Turbine flow meters are designed to measure the flow of liquid and gas in pipes on a volumetric basis and they do so accurately.

The flow meter housing contains rotor blades attached to a rod and mounted on bearings in order to spin. As the fluid moves through the meter, the rotor blades turn. The faster the fluid moves, the faster the rotor blades turn.

The rotating speed of the blades is measured by attaching a magnet onto the blades themselves. These magnets then pass a piece of metal embedded at a designated point within the casing. This passing contact allows us to calculate the time passing between each contact which in turn allows us to calculate the speed of the fluid passing through. This particular system means that regardless of the fluid’s direction, the meter works in exactly the same way.

In essence, a turbine flow meter is a tube with a propeller. For the flow meter to work properly, it is essential that the turbine rotates freely. Because of its simple but effective design, the pressure rarely drops except very slightly. As such, gas turbine flow meters and water turbine flow meters are one of the most accurate tools available for measuring fluid displacement.

Meter inspection
Check that the rotor turns freely. If necessary, lubricate the bushings with a drop of light oil to do this test. The meter is shipped from the factory already lubricated. Be careful if you use compressed air, do not exceed the maximum speed of the rotor. This condition can deteriorate the bushings. Verify that the retention latches are properly installed. The tips of the same should go towards the inside of the meter, avoiding the rotation of the supports. Gather the information provided with your meter and verify that all the technical characteristics of the meter are compatible with the process (minimum and maximum flow; pressure and temperature range; compatibility of materials, body, internals, seals and other data if any).

Meter location
The different types of mounting architecture and accessories used in the pipes generate unwanted disturbances and turbulence when measuring the circulating flow. Sometimes these disturbances cause the angle of attack of the liquid jet on the rotor blades to differ with the calibration conditions in the factory and mainly when there are variations in flow. To this end, to ensure the correct operation of the meter, a minimum of ten straight pipe diameters must be provided before the meter and five after it. When the pipes incorporate accessories such as elbows, tees, reductions or valves, these dimensions will be greater. The figure indicates the minimum distances required for some typical cases.

If you do not have the necessary distance, it is advisable to consult the factory on the particular case. The meter MUST NOT BE INSTALLED in the immediate vicinity of the pump, this distance should be as long as possible. Nor should it be installed near discharge outlets that do not ensure a minimum pressure drop at the meter outlet (approx. 0.2 bar), this will prevent the rotor from accelerating unduly. The meter will work correctly in horizontal pipes, and can also be applied in vertical pipes, only with upward flow. If the totalizer or transmitter unit is not placed on the meter, the primary signal of the turbine (millivolts a.c.) must be connected with a meshed instrument cable, to avoid noises of an electrical nature that could distort the measurement.

This distance should not exceed 20 to 30 meters in those meters whose signal at minimum flow is of the order of 20 mV. ef.

If in the installation area, there are possibilities of generating loud noises, such as transformers, motor or coil fields, contactors or relays, etc., which may incorporate pulses or cancel part or all of the turbine signal, it is advisable to use of a signal amplifier. Special care must be taken in those places where there are variable speed drives.

Commissioning
When the pipes are new or have been out of service due to modifications, before installing the meter, it is advisable to circulate a sufficient quantity of liquid to wash the pipe and thus ensure that remains of slag, mechanical material or others, do not go to the meter, which may cause breakage or miscalibration. When the liquids are clean, the installation does not require the use of a previous filter. It is only necessary if it carries particles, threads or lint that could jam or damage the meter. The design of the pipe must be prepared so that there is no back flow of liquid. This does not affect the meter, but it will be counted as dispensed liquid. Verify that the meter inlet is in the correct direction and that the seals or gaskets are in place. If in doubt, remove the meter, check and install it again. Check that the nuts and threaded connections are securely fastened. Never leave valves or connections that by mistake or ignorance, could be opened causing accidents. Always install firmly attached plugs or caps.

Be very careful, in those pipes subject to vibrations, if necessary, taper the same to avoid them. With everything in condition, start the fluid circulation in a moderate way, until all the air is purged from the pipe; otherwise it will be computed as liquid. Avoid any water hammer due to the violent opening or closing of valves. Adjust the valves to the desired flow rate. Before leaving the meter running for good, check that there are no leaks.

Maintenance Routine
When the liquids are clean and free of impurities, such as lint, threads, or suspended solids, that can jam or damage the meter, it will work for long periods without having to be removed from the pipe. Generally a visual inspection of the rotor bushings can be performed, depending on the time interval, on the demands of your process. With the meter removed, check that the rotor turns freely, without friction, or has excessive precession.

Verify that the blades of the same are not damaged or twisted, decalibrating the meter.

CAUTION: If you use compressed air to rotate it, do not apply too much speed which could damage the bushings.
When removing the interior kit from the meter, it is advisable to always operate on the inlet lock, in case it was incorrectly installed by mistake, the interior kit will also be retained inside the body by the outlet lock. When reinstalling the inner kit, check that the direction of the indications (engraved letters and / or arrows) on the supports and the rotor coincide with the direction of flow. Verify that the retention latches are properly installed. The tips of the same should go towards the inside of the meter, avoiding the rotation of the supports.

Repair
If for any reason you remove the rotor, be sure to install it in the same position as it was calibrated at the factory. Installing it backwards may cause an error of approximately 1%, (typical of each meter). If the bushings or interior parts show any anomaly, you can purchase a replacement interior kit and replace it, and it is advisable to send the flowmeter to the factory for repair and correct calibration.

FAQ

Q: What is the straight run requirement for thermal mass flow meter?

A: How much straight run is available? To meet their laboratory-calibrated performance specifications in their actual field installation, thermal mass flow meters require a repeatable flow profile. This will naturally occur with 15d to 20d of upstream straight run and 5d to 10d of downstream straight run.

Q: What are the limitations of thermal mass flow meter?

A: The thermal mass flow meter can only accurately measure the gas (or gas mixture) for which the meter was calibrated. The thermal mass flow meter needs to be calibrated or have its calibration verified periodically. The thermal mass flow cannot accurately measure gas when its composition changes.

Q: How accurate is a thermal mass flow meter?

A: Thermal mass flowmeters prices are much more affordable. They are typically preferred for measuring smaller flow rates at low pressure. However, as they are affected by variations in density, temperature, and pressure, they require a real flow for calibration, to reach high accuracy (<1% for 100% H2).

Q: How does a thermal mass meter work?

A: Thermal mass flow meters measure the heat transfer as the gas flows past a heated surface. The gas molecules create the heat transfer, so the greater the number of gas molecules in contact with the heated surface, the greater the heat transfer.

Q: What is calibration of thermal mass flow meter?

A: The calibration process involves placing the sensor in one of several different test sections, flowing a known amount of gas through the pipe, and then measuring the signal to obtain the desired overheat. These measurements occur at least 12 times over the operating range.

Q: What is the formula for thermal mass flow meter?

A: This heat transfer process is non-linear, and the corresponding equation differs from the one above as follows: m0. 8 = Kq/(Cp(Tw – Tf)). This flow meter has two operating modes: one measures the mass flow by keeping the electric power input constant and detecting the temperature rise.

Q: What is the turndown ratio of thermal mass flow meter?

A: A thermal mass flow meter has a turndown ratio of 1000:1. An orifice plate meter has a practical turndown ratio of 3:1. A turbine meter has a turndown ratio of 10:1. Rotary positive displacement meters have a turndown ratio of between 10:1 and 80:1, depending on the manufacturer and the application.

Q: How do you determine when it is the correct time to calibrate a flowmeter?

A: Some flowmeters require calibration only once every 3-4 years. In other circumstances, more frequent calibration, possibly even monthly, may be required to maintain a safe, efficient, or regulatory-compliant operation. Calibration intervals might also fluctuate based on usage or historical performance.

Q: How do you install a thermal mass flow meter?

A: 1, Weld the socket on the pipe. 1), Weld the MNPT 1/2” socket on the pipeline vertically.
2, Preparation before drilling. 1), Connect the 1/2” ball valve on the socket.
3, Drill a hole with the hot tap hole opener, Ø 13mm (± 0.5 mm).
4, Calculate the insertion depth.
5, Insert the thermal mass flow meter sensor.

Q: What is the difference between thermal mass flow meter and Coriolis mass flow meter?

A: Coriolis flow meters allow the direct measurement of mass flows. Direct mass flow measurement eliminates inaccuracies caused by the physical properties of fluids. Thermal flow meters, on the other hand, allow indirect measurement of mass flows.
