Correct use and installation method of integrated orifice flowmeter
Integrity Orifice Flowmeter Correct Use and Installation Method Introduction Jinhu Hongchuang Instrument Co., Ltd. has extensive experience and installation experience, engaged in instrument production for many years, the main products are: integrated orifice flowmeter, vortex flowmeter, electromagnetic flow Meter, metal tube float flow meter. What are the precautions for using integrated orifice flowmeters? The integrated orifice flowmeter is a new-generation flowmeter that integrates flow, temperature and pressure detection functions, and can automatically compensate for temperature and pressure. It adopts advanced microcomputer technology and new micro-power technology, with powerful functions and compact structure. The operation is simple and easy to use. The integrated orifice flowmeter consists of sensing, transmission, and operation display. The three major parts are mainly applicable to industrial measurement of saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gas, and hot water, and the flow rate of the above fluid is measured. The use of on-line automatic controls for display, metering and production processes can be used. The most important thing to pay attention to when it is put into operation is that it must be filled with water or injected high-temperature steam before it can be started. The straight pipe section before and after the orifice piece flowmeter must be straight. The straight pipe piece used for installing the throttle piece should be smooth. If it is not smooth, the flow coefficient should be multiplied by the roughness correction and sparsity. A lengthy straight pipe section is required before and after the throttle piece. When the upstream side of the throttle piece is an open space or a large container with a diameter larger than or equal to 2D, the straight pipe length between the open space or large container and the throttle piece shall not be less than 30D (15D). . If there is any other local resistance between the throttle and the open space or large container, except from the open space to the joint, the length of the minimum straight pipe section 1 is provided between the throttle and the local resistance. The total length of straight sections between flow elements must not be less than 30D (15D). How to properly use the integrated orifice flowmeter: Jinhu Hongchuang Instrument Co., Ltd. The following details for everyone: 1. Pressure tube system filled with cold water as a pressure medium, measuring high-temperature steam is generally guided by cold water pressure. In the case of no steam in the pipeline, open the valve, pressure valve and balance valve, close the drain valve, and inject cold water directly from the condensate filling hole until it is fully filled. Of course, it is also possible to close the balance valve and the pressure valve, and open the valve once to introduce high-temperature steam and slowly cool it into water. This method is generally not adopted because the steam temperature is too high and it is easy to damage the instrument. Special attention should be paid to the fact that when the high-temperature steam is measured, the pressure guiding pipe is not filled with water or the temperature is too high. Measure compressed air, cold water directly by the medium pressure. 2. When the differential pressure transmitter exhausts or discharges fluid, and the pressure guiding tube is filled with water, a small amount of gas must be accumulated in the pressure chamber of the differential pressure transmitter to affect the pilot pressure and must be eliminated. Unscrew the positive and negative pressure bolts at the bottom of the chamber. Normally, the newly commissioned instrument does not need to be drained. Check the pilot line system without any leakage, close all valves and be ready for operation.
