The liquid turbine flowmeter uses a turbine for measurement. lt first converts the flow rate into therotational speed of the turbine, and then converts the rotational speed into an electrical signal proportionalto the flow rate. This type of flow meter is used to detect instantaneous flow and total accumulated flow.Its output signal is frequency and is easy to digitize. Liquid turbine fiow meters are widely used inpetroleum organic liquids, inorganic liquids, liquefied gas, natural gas and cryogenic fluids.
