4-20mA Output Portable Clamp On Ultrasonic Flow Meter

Steps to the installation of the flow meter:

Locate an optimal position where the straight pipe length is sufficient, and where pipes are in a favorable condition, e.g., newer pipes with no rust and ease of operation. Clean any dust and rust on the spot where the flow meters are to be installed. For a better result, polishing the pipe's outer surface with a sander is strongly recommended. Apply adequate ultrasonic couplant onto the flow meter transmitting surface as well as to the installation spot on the pipe surface. Make sure there is no gap between the flow meter transmitting surface and the pipe surface.

Extra care should be taken to avoid any sand or dust particles left between the pipe surface and the flow meter surface.
Horizontally lined pipes could have gas bubbles inside the upper part of the pipe. Therefore, it is recommended to install the flow meter horizontally on the side of the pipe. There are three ways to mount the flow meter on the pipe: By magnetic force, by the clamp-on fixture, and by hand. If the pipe material is metal, the magnetic force will hold the flow meter on the pipe. Otherwise, you may either simply hold the flow meter handle and press it against the pipe (for s-type only) if you just need a quick measurement, or you may use a metal strip or the provided clamp fixture to install the flow meter.
