How to apply the orifice flowmeter antifreeze breaker

Kaifeng Cologne Flow Meter Co., Ltd.   How to apply the anti-freeze breaker to the orifice flowmeter for professional technicians

　　 The orifice flowmeter uses a unique anti-freeze blocker. When measuring steam, it does not need heat, heat preservation and condenser, which greatly simplifies the layout and facilitates field equipment. Not only does it save a lot of power, but the flowmeter maintenance is greatly reduced. In the traditional orifice flowmeter , in order to condense the steam in the pressure guiding tube and make the condensate surface in the positive and negative pressure guiding tubes have equal heights, and maintain stability, both in the positive and negative pressure guiding pipelines Each is equipped with a condenser. In order to ensure the normal operation of the differential pressure transmitter in the cold environment, it is also necessary to be equipped with heat-insulating insulation equipment, which has a large layout and waste of power.

The fluid filled in the orifice flowmeter pipe, when they flow through the saving device in the pipeline, the flow beam will be partially shortened in the saving part of the saving device, so that the flow rate is increased, the static pressure is low, so it occurs before and after saving the piece. The pressure drop, that is, the pressure difference, the greater the flow rate of the medium activity, the greater the pressure difference that occurs before and after the saving of the piece, so the orifice flow meter can measure the pressure difference to measure the flow rate. This measurement method is based on the law of energy conservation and the law of activity continuity.

　　 Orifice flowmeter, also known as differential pressure flowmeter, consists of primary and secondary equipment and is widely used for flow measurement of gases, vapors and liquids. It has the characteristics of simple layout, convenient repair, unchanged function, and firm use. The orifice plate saver is installed inside the pipeline. Since the aperture of the saving member is smaller than the inner diameter of the pipeline, when the fluid flows through the saving member, the cross section of the stream is shortened and the flow velocity is accelerated. The static pressure drop of the fluid at the back end of the piece is saved, so that a static pressure difference occurs before and after the saving piece, and the static pressure difference and the fluid flow rate of the fluid have a determined value contact and fit.

The equipment is widely used in process control and measurement in petroleum, chemical, metallurgy, electric power, heating, water supply and other fields. Orifice flowmeter is widely used in various fields of the national economy such as coal, chemical industry, transportation, construction, textile, food, medicine, agriculture, environmental protection and daily life of the people. It is the development of industrial and agricultural production, saving energy and improving product quality. Important tools to improve economic efficiency and management level play an important role in the national economy.
