We are the one of India's Leading Manufacturesr for Flow Measuring Instruments,Pressure Measuring Instruments,Level Measuring Instruments,Temperature Measuring Instruments etc.

In Ori Flowmeters consisting of an plates by which flowrate is measured with a small sized flow meter set to a by pass pipes, the flow measurement even for large sized lines can be economically conducted.In addition to the local indication type, different types of outputs as require to the customer
The ori flow meter measures flow by inserting an orifice flowmeters at part the piping, generating differential pressure before and behind the orifice flowmeters by means of the flow, and extracting this differential pressure by a suiatable method.

Q : Volumetric flow
C : Flow co-efficient
F : Cross sectional area of orifice hole
g : Acceleration of gravity
P1-P2 : Differential pressure
Y : Specific weight of fluid

ori flow meter is used in bigger line size with high flow rate and high temperature like example: Air,steam,water etc.
therefore if a by pass pipe connecting the before and behind point of the main orifice is installed and the flow is branched to that pipe to overcome these disadvantage, that flow becomes propotional to the differential          
Differential pressure (p1-p2) of main orifice flowmeters and the flow Q have shown in the equation given below. the flow is proportional to the square root of the differential pressure
The generated differential pressure is sent to a manometer or other differential pressure gauge and a differential flow meter can be formed by attaching a flow scale to this gauge. however,since the flow meter indication is a square root scale reading is difficult. more over, incase of remote transmission it is incovenient because the evolution operation is performed to obtain linear relation.
