Orifice-type steam flowmeter application overview and features Orifice-type steam flowmeter is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. The orifice flow meter throttling device includes a ring chamber orifice plate, a nozzle, and the like. The orifice flowmeter throttling device is used with the differential pressure transmitter to measure the flow of liquid, steam and gas. The orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other departments. Orifice-type steam flowmeter is a new-generation orifice flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and new micro-power technology. Strong function, compact structure, easy operation and easy to use. Orchard steam flowmeter features 1. The orifice flowmeter throttling device structure is easy to copy, simple, firm, stable and reliable, long service life and low price. 2. Orifice plate calculation adopts international standard and processing 3. Wide application range, all single-phase flow can be measured, and some mixed phase flow can also be applied. 4. The standard type throttling device can be used without real-flow calibration. 5, the integrated orifice flowmeter installation is simpler, no need to lead the pipe, can be directly connected to the differential pressure transmitter and pressure transmitter. 6, using imported monocrystalline silicon intelligent differential pressure sensor 7, high precision, perfect self-diagnosis function 8, intelligent orifice flowmeter intelligent orifice flowmeter, its range can be self-programmed adjustment. 9, intelligent orifice flowmeter can display cumulative flow, instantaneous flow, pressure, temperature. 10. With online and dynamic full compensation function, the intelligent orifice flowmeter also has the characteristics of self-diagnosis and self-setting annular orifice flowmeter. 1. It is suitable for measuring dirty media such as steam, gas and cooling water. The special structure of the annular orifice plate "circumferential circulation, intermediate blocking" makes the condensed water formed by the steam flowing unimpeded and steam stop in time, thereby improving the work reliability and measurement accuracy. 2. Suitable for flow measurement of high temperature and high pressure fluids. When the annular orifice plate measures high temperature fluid, the periphery of the flowmeter is in a free state, the temperature expansion only changes the outer shape, does not change the sharpness and shape of the edge, so the flow coefficient is not changed, and the measurement accuracy is not affected; when the high pressure fluid is measured, the flow is measured. The plate is inside the pipe, regardless of the level of static pressure, reducing the processing cost. 3. It is more reliable than the round hole plate and eccentric plate, and the measurement is accurate. The annular orifice plate is used to measure the fluid flow rate, and it is not easy to block the pressure tapping hole. Because of the simple geometric shape, it can be precisely processed and assembled, and the measurement accuracy is easily improved. 4. Use a pressure equalizing ring structure to reduce the source of measurement error. 5. Using a differential pressure transmitter with a remote transfer cassette, it is possible to measure the flow of dirty media such as residual oil and heavy oil.
