portable ultrasonic flow meter


This portable ultrasonic flow meter consists of two clamp on transducers (install on the closed pipe) and of a digital converter operating on internal battery or on a power source.
This non invasive ultrasonic flow meter uses the transit time ultrasonic signal technology to measure flow of liquids on any pipe size.
It allows a wide range of applications due to its ability to adapt to all types of conditions and a wide choice of liquids and pipe sizes. 

Features of the portable ultrasonic flow metersFeatures of the portable ultrasonic flow meters

  • Accurate measurement of liquid flow rate
  • No need to cut the pipe wall thanks to clamp on transducers
  • Quick installation
  • No moving parts
  • No pressure loss
  • Bi-directional large flow speed measurement from -32 to +32 m/s.


A powerful and user-friendly portable ultrasonic device that is very appreciated by anyone wishing to measure flow in the field: a large colour LCD graphic display, a set of drop-down menus and a reduced number of keys make this unit a simple flow meter. It can measure bi-directional flow speeds from -32 to +32 m/s.

Energy calculation function available

This function of ultrasonic portable flow meter allows to measure the thermal energies exchanged via fluid used in air-conditioning systems HVAC.
The electronic transmitter calculates the thermal energy consumption based on the forward flow temperature, the return flow temperature, and the liquid flow rate.
This way the ultrasonic flowmeter can calculate the energy efficiency of the heating system and help you to save energy.

Energy calculation function available

Application of ultrasonic flow meter portable Application of ultrasonic flow meter portable

  • Leak detection of any liquids on pipeline
  • Temporary flow measurement of liquid for maintenance purpose for any pipe sizes
  • Volumetric flow in clean liquids and those with small amounts of suspended solids or aeration such as surface water or raw sewage
  • Non invasive flow rate calibration of existing magnetic flow meter
  • Pump flow control
  • Measuring and balancing district heating network

Note : This device is not a portable gas flow meter and not suitable for gas applications like compressed air
