Litre Meter specialise in the design, manufacture and supply of flowmeters. Listed below are all the flow meters within our range that are suitable for tanker loading:
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.
Helical Screw Meter
Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. Inside the chamber, a rotating/reciprocating mechanical unit is placed to create fixed-volume discrete parcels from the passing fluid.
The helical screw principle uses 2 counter rotating gears to form a continuous constant volume cavity. The SRZ is a stainless steel version suitable for high viscosity and abrasive media flow metering. 0.04 to 400 litres per minute, +/-0.1% accuracy, +/-0.05% repeatability. Housing in 316L and 303 with screws in 1.4122 (430), tungsten carbide bearings and FKM or PTFE seals. Pressures to 400 bar, -40°C to 150°C.
