Flow / Air Velocity / Flow Transmitter / Air Volume


Porous Orifice Plate Balanced Flowmeter

FOM09 Balance the flowmeter can maximize the rectifier into ideal fluid flow field in balance, to measure the differential value according to the Bernoulli equation to calculate the flow in the pipeline. Balance disc throttling of flow sensor is a porous rectifier, installed on the cross section of the pipeline, the size and distribution of each hole is based on the special formula and test data, and custom, called the function. Balance meter when the fluid through the function of the disc holes, the fluid will be balanced rectification, eddy current is minimized, form the approximate ideal fluid, through pressure device, can obtain the stability of the differential pressure signal, according to the Bernoulli equation, to calculate the volume flow to mass flow.
