Introductions
WESDUN portable ultrasonic flow meter is a type of portable instrument for non-invasive, quick flow and energy measurement with clamp-on technology for many types of piping. Portable ultrasonic flow meter support quickly verify the flow reading of another meter and to data log flow system values over an extended time period.
The meter can be easily moved and installed in different pipes and convenient to carry site to site. The innovative design includes matched precision transducers and signal processing circuitry to accurately measure the flow of most liquids over a wide range of velocities. Its portability makes it an excellent choice for measuring flows throughout the plumbing infrastructure to verify sensor pump and valve performance.

Installation
It’s better to install the flow meter indoors; if you have to install it outdoors, you should take measures to avoid direct sunlight or rainwater.
The flow meter shall be installed away from high temperature, thermal radiation from equipment or corrosive gas.
Ultrasonic flow meters can’t be installed nearby motors, transformers or other power sources that are easy to cause electromagnet interference. DO NOT install ultrasonic flow meters nearby frequency converters or DO NOT connect it with the distributing cabinet of frequency converters to avoid interference.
In convenience for installation and maintenance, keep sufficient space around the flow meter.
