Flowma WUF 300 J Portable Ultrasonic Flowmeter


Flowma WUF 300 J Portable Ultrasonic Flowmeter

WUF 300 J is a full function handle transfer time ultrasonic flow meter. No matter you want to quickly verify the flow reading of another meter or to data log flow system values over an extended time period, the FLOWMA WUF 300 J is the suitable tool.

The WUF 300 J portable meter has the clamp on transducers no tapping or cutting is required, just clamp outside of the pipe. The meter can be easily moved and installed in different pipe and convenient to carry site to site.Its portability makes it an excellent choice for measuring flows throughout the plumbing infrastructure to verify sensor, pump and valve performance.


  • Easy to install, reduced installation time and cost.
  • No pressure head loss, No moving parts to maintain or replace.
  • BTU function is an option. WUF 300 J could be used as a portable ultrasonic energy meter.
  • Powerful data storage and also support the data sheet analysis software.


WUF 300 J portable ultrasonic flow meter widely application in oil industry, water treatment, pure water, chemical and etc.

Measuring Principle

Transfer time technical means the ultrasonic signal from the transducer is transmitted and received through the moving liquid, there will be a difference between the upstream and downstream transit time, which can be used to calculate flow and velocity.

Flowma WUF 300 J Portable Ultrasonic Flowmeter

An ultrasonic meter equipped with heat flow capabilities measures the rate and quantity of heat delivered or removed from devices such as heat exchangers. By measuring the volumetric flow rate of the heat exchanger liquid, the temperature at the inlet pipe and the temperature at the outlet pipe, the energy usage can be calculated.
