Litre Meter specialise in the design, manufacture and supply of flowmeters. The vortex meter from Sierra can measure steam flow with no moving parts over a wide turn down.
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.
