Turbine flow meter are used for precise measurement of low viscosity fluids such as water, fuels, solvents, demineralised water, chemical, or any fluids which has viscosity of not more than 30 cSt.
A variable area meter is a meter that measures fluid flow by allowing the cross sectional area of the device to vary in response to the flow, causing some measurable effect that indicates the rate.
A mass flow meter is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time.
Vortex flowmeters, also know as vortex shedding flowmeters or oscillatory flowmeters, measure the vibrations of the downstream vortexes caused by the barrier placed in a moving stream.
Coriolis flow is guided into the U-shaped tube. When an osillating excitation force is applied to the tube causing it to vibrate, the fluid flowing through the tube
BTU or British thermal unit flow meter measures both the temperature and the flow rate of the fluid flowing through it. BTU flow meters typically use precision RTD elements to measure temperature while the flow rate measurement is done by electromagnetic, turbine or ultra-sonic meters.
