The correct use and installation method of the integrated orifice flowmeter The integrated orifice flowmeter is mainly used for sensing, transmission and calculation. It is mainly suitable for saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gas and The industrial measurement of hot water can be used for the flow measurement, display, measurement of the above fluids and on-line automatic control of the production process. 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.

Package and Storage for Zirconium Oxchloride :
25kg or 1000kg net in woven plastic bag with inner double plastic bags or packed as the requirements of clients.
(1).To be protected from moist and prevent getting in touch with general metals in storehouse
(2).To make sure that the container does not leak, collapse, fall, or damage during transportation.Prevent heat, rain, sun exposure during transportation.Prohibit mixed loading and mixed transportation with oxidizing agent.
The straight pipe section before and after the throttle plate of the integrated orifice flowmeter must be straight. The straight pipe section used for installing the throttle piece should be smooth. If it is not smooth, the flow coefficient should be multiplied by the roughness correction sparse. Before the throttle element, a straight pipe section of sufficient length is required. When the upstream side of the throttle piece 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 piece 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).
How to use the integrated orifice flowmeter correctly: 1. The pressure guiding pipe system is filled with cold water as the guiding medium, and the high temperature steam is generally guided by cold water. In the case where the pipeline does not deliver steam, open the valve, pressure valve and balance valve, close the drain valve, and inject cold water directly from the condensate tank water injection hole until it is fully filled. Of course, it is also possible to close the balancing valve and the pressure valve, and open the primary valve to introduce high-temperature steam and slowly cool it into water. This method is generally not used because the steam temperature is too high and it is easy to damage the meter. In particular, it should be noted that when the high temperature steam is measured, the pressure guiding tube is not filled with water or the temperature is high and it is strictly prohibited to put into operation. The compressed air and cold water are measured directly by the medium. 2. The differential pressure transmitter is exhausted or drained. After the pressure guiding tube is filled with water, a small amount of gas is sometimes accumulated in the pressure chamber of the differential pressure transmitter to affect the pressure guiding, and must be excluded. Unscrew the bolts in the lower part of the positive and negative pressure chambers. Generally, the newly put into operation of the instrument does not need to drain. Check the pilot line system without any leakage, close all valves, ready to put into operation
