Orifice flowmeter is a collection flow, temperature and pressure detection function. The integrated orifice flowmeter integrates flow, temperature and pressure detection functions, and can perform temperature and pressure (supporting armored thermal resistance, pressure transmitter, and difference). Pressure transmitter) Automatic compensation of the new generation of flowmeters, using advanced microcomputer technology and new micro-power technology, powerful, compact, easy to operate, easy to use.
The straight pipe section before and after the orifice of the orifice flowmeter must be straight. The straight pipe section used for the installation of the throttle should be smooth. If it is not smooth, the flow coefficient should be multiplied by the roughness correction sparse. Before the throttle member, a straight pipe section of sufficient length is required. When the upstream side of the throttle member is an open space or a large container with a diameter ≥ 2D, the open space or the straight pipe length between the large container and the throttle member shall not be less than 30D (15D). . If there are other local resistance members between the throttle member and the open space or the large container, then from the open space to the section, except that the minimum straight pipe length 1 is attached between the throttle member and the local resistance member. The total length of the straight pipe between the flow pieces shall not be less than 30D (15D).
The orifice flowmeter is mainly used for industrial metering of saturated steam, superheated steam, compressed air, heat transfer oil, mixed non-flammable explosive gas and hot water by sensing, transmission and operation display. Measurement, display, metering, and online automatic control of the production process can be used. The most important precaution for putting into operation is to start the operation after the pressure pipe is filled with water or the injected high temperature steam is cooled.
