一、Working principle and composition: ultrasonic meter is to measure the cold heat meter, its main components are paired temperature sensor, ultrasonic flow meter and calculator, paired temperature sensor to measure the temperature of water and backwater.Ultrasonic flowmeter to measure fluid flow flowing through a pipe, it is using ultrasonic transducer to send and receive ultrasonic, and detect the propagation time difference in the downstream and upstream medium to medium velocity have been measured, and flow through the calculation of flow velocity, the two after the data was collected to calculators calculate the users use the cold heat, and displayed on the LCD.
二、Maintenance of the plug-in ultrasonic heat meter: 1、 After the meter is installed and used, the operation of the meter and the battery voltage should be checked regularly.2、When the flow is significantly reduced and the heating is affected, sewage and cleaning of the filter should be carried out.3、After a few years of operation, when the data on the display screen is not clear, it may be that the battery is low, and the battery should be replaced immediately by specialized technical personnel.4、table is a measuring instrument, must be in accordance with the national standards for regular verification, and replace the battery when verification.
