Request info

The XRATE Liquid meter from Xsens provides accurate, reliable and cost effective flow measurement for any liquid. The meter is clamped to the outside of a pipe and measures liquids with ultrasonic signals straight through the pipe wall. It measures the transit time of acoustic signals through the liquid over the full bore of the pipe, measuring the full velocity profile to achieve high accuracy of 1% of flow. It typically provides an output in m3/hr or any other metric that clients require.

The clamp on design allows for easy installation (2-3hrs) and it can be installed close to bends and valves if needed. Since the meter is not in contact with the liquids, it is not affected by erosion, corrosion, waxing, scaling or leakages. This makes the meter very reliable and robust, with minimal maintenance required.

This meter is used to measure oil, water and chemical flow rates in tough, industrial environments. It has a lightweight design and is available from 1.5inch to 30inch as standard and bigger on request. It comes with an integrated flow computer to provide the required outputs through analogue 4-20ma or digital Modbus signals.

There is no limit on pressure, viscosity, density or sour service as it does not affect the measurement or the meter itself. Turn down ratio is 1:400 meaning we can measure 0,1 to 40 m/s. There is also no need for static mixers or flow straighteners as the meter measures the full velocity profile.

For remote installations we can offer WiFi, cellular and satellite signals while adding solar panels for power. The meter can be accessed remotely through internet connection to be monitored and updated if needed.

Local displays for local reading of measurements can be added on request.
The meter is Ex Zone 1 and 2 certified for hazardous areas and can also be supplied without such certification to reduce cost.
