Orifice Plates

Product Features

The OTD-OP series orifice flowmeter is a standard throttling device. It is the product with simplest structure and strongest application among all throttling devices and is widely applied for flow measurement of varied liquids and gas, The orifice structure varies due to the different nominal pressure, inside nominal diameter and pressure taking mode, its design, manufacturing and use meet the international standard ISO5167.

Standard orifice, according to the common pressure taking mode, is classified in three types: corner joint pressure taking (includes ring chamber pressure taking and independent borehole pressure taking two kinds of), flange pressure taking, Radius pressure taking (D and D/2 pressure taking).

The orifice plate is basically a thin metal plate with a hole bored in the centre. When a liquid / gas passes through an Orifice Meter, there is a drop in the pressure between the Inlet section and Outlet Section of Orifice Meter. This drop in pressure can be measured using a differential pressure transmitter to determine the flow rate of the fluid.

Simple structure, convenient for assembly, correct measurement, without actual flow calibration;

Low manufacturing cost, broad applicable range and no maintenance requirements.

Corner tapping, flange tapping, Radius tapping;

Accuracy is between ±0.5%~1.5%;

The supply includes complete installation accessories , the design and calculation can be done for the customer.

The Plate Handles are stamped with relevant information such as Tag No, Line I.D, bore size as an example.
