Liquid Flow
0.5 ml/min to 500 l/min
Our UKAS, ISO 17025 accredited laboratory can cover the following range 0.5 ml/min to 500 l/min
The Labcal gravimetric water flow calibration facility uses the principle of mass and time to measure liquid flow. This method is one of the most accurate for the calibration of liquid flow meters.
Typical flow meters we can calibrate are:
- Variable area glass and metal tube types
- Positive displacement
- Turbine
- Mass flow meters including Coriolis
- Vortex shedding
- Ultrasonic
- Target
- Magnetic

Gas Flow
Range 0.025 ml/min to 13000 l/min
Our UKAS, ISO 17025 accredited laboratory can cover the following range 0.025 ml/min to 13000 L/min
Calibration can be undertaken on air, nitrogen, oxygen, helium, argon, carbon dioxide and any other inert gases.
Types of flow meters include:
- Variable area flow meters (glass and metal tube type)
- Dry and Wet gas flow meters
- Positive displacement flow meters
- Turbine flow meters
- Laminar flow elements
- Mass flow meters and controllers
- Bubble and piston flow meters
- Nozzles
- Orifice plates
- Vortex shedding flow meters
We also supply a range of VA FLOW METERS

Pressure
0 to 1400 bar
Our UKAS, ISO 17025 accredited laboratory can cover the following range 0 to 1400 bar
We specialise in the accurate calibration of low differential pressure which is essential for measuring the pressure in ducts and the calibration of pitot tubes. We utilise several pneumatic and hydraulic dead weight testers which measure gauge and absolute pressures from a fraction of a Pascal to 1400 bar.
Typical pressure instruments we are able to calibrate are:
- Pressure gauges
- Digital pressure indicators
- Barometers
- Differential pressure indicators
- Liquid manometers
- Micro manometers
- Pressure Calibrators
- Pressure Transducers
- Pressure Transmitters
- Pressure equivalent calibration of dead weight testers (pressure balance with mass set)
