Pressure & Flow Measurement
Our expertise in the manufacture of highly sensitive differential pressure sensors allows us to provide flow and pressure measurement solutions with unparalleled accuracy at the low-end of the scale.
Our pressure transmitters start at a range of just ±50 Pa, with an accuracy of better than 0.25% of reading.
Through our varied range of Pitot tubes, laminar flow elements, flowmeters and transmitters, we can offer a complete solution for low-pressure and low-flow measurement.

Calibration
We have been raising the standards of accuracy and calibration in the field of ultra-low range differential pressure and air flow measurement for decades.
Whether you are looking for a service to calibrate your instruments or a calibrator to do the work yourself, Furness Controls can help.
Our Calibration Laboratory is accredited for ultra low range differential pressure from 0.001 Pa up to 40 kPa, for gauge pressure up to 4 MPa, and air and gas flow from 0.1 ml/min to 40000 litres/min

Leak testing, flow testing and ultra-low pressure measurement
For more than 60 years Furness Controls has designed and built leak testers, flow testers and differential pressure instruments for manufacturers around the world. Our differential pressure leak testers can detect pressure changes as small as 0.1 Pa, which means leak rates down to around 0.01 ml/min. They do this on the production line, without tracer gas, and without damaging the part.

Leak testing for electric vehicles and batteries
EV battery enclosures, cooling plates, glycol circuits, inverters and motor control electronics all need reliable sealing. Furness leak testers check large-volume battery enclosures with continuous pressure testing (FCO794), and small sealed electronics with high-sensitivity testing (FCO720).
Which leak test method is right for your part?
-
Differential pressure decay leak testing
We pressurise the part, isolate it and measure any drop in pressure against a reference. It's highly accurate, repeatable and easy to automate.
-
Flow and blockage testing
We check the flow through valves, filters, tubing and nozzles against a minimum or maximum limit.
-
Sealed-part testing.
We check airtightness of hermetically sealed components from 0.1 ml internal volume.
We have a network of global distributors bringing our testing knowledge to factories around the world
