FlowLabPro an Easily Transportable Automatic Low Flow Meter Calibration Stand

The FlowLabPro is a fully automated volumetric fluid calibration rig, allowing multiple meters to be calibrated on multiple fluids without human interaction.

The Litre Meter temperature-controlled volumetric low-flow calibration rig FlowLabPro delivers automatic calibration of flow meters and instrumentation within a flow range of 0.0006 to 200 l/hr to an accuracy of ±0.2 per cent and a repeatability of ±0.05 per cent.

Accuracy is much greater and uncertainty is much lower than was previously achievable using volumetric calibration.

All the associated tanks, pumps, ultrasonic sensors, pressure gauges and temperature probes are housed in a compact and manoeuvrable temperature-controlled cabinet.

Equipped  with  a  316L  stainless  steel  measuring  tube  and  a  state  of  the  art  sensor  it  can  measure  with  ±0.1%  accuracy

Now commercially available from Litre Meter, the new volumetric low-flow calibration rig can measure any fluid type within reason and features a reverse flow testing facility.

Charles Wemyss, CEO of Litre Meter, said: “We recently introduced our LF03 low-flow VFF rotary piston meter taking the capability of our VFF flow meter range down to lower flows than ever before – for example, on a fluid with a viscosity of 10 cSt the LF03 will measure down to 0.06 litres/hour at pressures of 1 bar right up to 4,000 bar.

“As a result of this innovation the next logical step was to develop a calibration rig capable of accurately measuring ultra-low flow rates. We were so happy with the results that the decision was made to make the volumetric low flow calibration rig available on the open market.”
