Litre Meter specialise in the design, manufacture and supply of flowmeters. The KEM HM turbine has been utilised over the last 4 decades for cryogenic flow metering. Our range has been enhanced by the Sierra vortex meter. Both are designed for flow metering of LIN/ LOX/ LAR (Liquid Nitrogen, Liquid Oxygen, Liquid Argon) down to -328Â°F (-200Â°C). Listed below are all the flow meters within our range that are suitable for cryogenics:
Capable of measuring the flow of gasses and liquids, our flow meters provide accuracy and efficiency. As all materials differ in characteristics, certain flow meters are best suited to certain materials. Below, you’ll find the best products for cryogenic flow metering.
The following flow meters are designed for measuring liquid nitrogen, liquid oxygen, and liquid argon down to -328Â°F (-200Â°C):
Vortex Mass Meters
Vortex and other types of ‘oscillatory’ flow meters utilize the behaviour fluid oscillations in order to derive flow rate. This technology works by inducing fluctuations in the fluid properties such as pressure, density or viscosity which can be converted into a flow rate. These flowmeters are normally calibrated on water. No moving parts and relatively tolerant to particulate flow these find many applications where temperatures are high or where other more traditional flowmeter technologies are out of spec. +/- 1.5% rate, 1/2″ to 8″ and insertion.
Inline ‘axial’ turbine flowmeters are velocity measuring devices – they measure the average velocity of a fluid flowing through the body of the meter. Mounted within the body of a liquid turbine flowmeter is a vaned rotor. The rotor is centred on a shaft and allowed to rotate on bearings. The shaft is supported in the housing by tube bundles that also provide a measure of flow conditioning for the fluid stream. Good for low viscosity epoxy and catalyst flow metering. Wide size range and excellent accuracy. 0.24-17 up to 3028-56775 litres/min. Overrange 150% intermittent. ±0.25% reading – typical. ±0.1% repeatability.
