Orifice flowmeter is a high range specific differential pressure flow device which is composed of standard orifice plate and multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter).The throttling device, also called differential pressure flowmeter, has simple structure, convenient maintenance and stable performance.
The standard orifice can be used to measure the flow of liquid, gas and steam in the pipeline.The standard orifice plate can adopt three kinds of pressure extraction methods: angular contact (including annulus pressure extraction), flange pressure extraction or d-d /2 pressure extraction.The standard orifice plates designed, manufactured and certified by the company do not need to be calibrated with real flow. The precision is high, the structure is simple and the manufacturing cost is low.

The standard orifice plate can adopt three kinds of pressure extraction methods: angular contact (including annulus pressure extraction), flange pressure extraction or d-d /2 pressure extraction.Our standard orifice plate without real flow calibration, high precision, simple structure, low manufacture cost, but the pressure loss in all standard throttle device is the largest, do not apply to the requirements of small pressure loss.

1. The standard throttling device is fully used and has been recognized by the international standards organization. It can be used without real flow calibration and is unique among flow sensors.
2. The structure is easy to copy, simple, firm, stable and reliable in performance and low in price;
3. Wide application range, including all single-phase fluid (liquid, gas, steam) and partial miscible phase flow. The pipe diameter and working state (temperature and pressure) of the general production process can be measured.
4. Test parts and differential pressure display instruments can be produced by different manufacturers separately, facilitating specialized scale production.

The standard orifice plate is widely used in petroleum, chemical industry, metallurgy, electric power, etc, used to measure the liquid and gas in the pipeline, the flow of steam.
