ATUF wall mounted ultrasonic flow meter is a type of instrument for non-invasive, quick flow and energy measurement with clamp-on technology for many types of piping. Wall mounted 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.

You could select the flow meter with an explosion-proof housing, and intrinsic safety explosion-proof flow meter with intrinsic safety design circuit to ensure its safety and flame-retardant operation. Each flow meter should have a nameplate clearly identifying its certifications. Please DO install and use the flow meter according to the explosion-proof grade and protection grade as shown on the nameplate.
To ensure measurement accuracy of the flowmeter, try to satisfy the following requirements on the length of straight pipe sections installed nearby the flowmeter: upstream >20D, downstream>10D.
