The correct use of orifice meter scale and installation method

Abstract: proper use and installation method of orifice meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Proper use and installation method of orifice flowmeter integration orifice meter consists of sensor, transmitting, operation shows three parts is mainly suitable for saturated steam and superheated steam, compressed air, mixed inflammable and explosive gas and hot water industry in measurement, of the above. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the orifice meter scale details on proper use and installation method of the article. Proper use and installation method of orifice flowmeter integration orifice meter consists of sensor, transmitting, operation shows three parts is mainly suitable for saturated steam and superheated steam, compressed air, mixture of flammable and explosive gas and hot water industry measurement, flow measurement, display, measurement of the fluid and the on-line automatic control of production process such as use all can use. Running zui important considerations is must in the guide tube filled with water or the injection of high temperature steam cooling before they can start the shipment. Integrated throttle orifice flowmeter of straight pipe before and after a paragraph must be straight, install the throttling parts with straight pipe should be smooth, if not smooth, flow coefficient should be multiplied by the roughness correction sparse. Throttling parts require a enough long straight pipe before and after the throttle upstream side for open space or diameter & ge; 2 d large container, the open space or a large container with throttling parts between the straight pipe length shall not be less than 30 d ( 15 d) 。 If throttling and open space or there are other local resistance between large container, except in throttling and local resistance parts has set rules annexed zui between small straight long 1, from the open space to the throttling parts between the straight pipe section chief, also should not be less than 30 d ( 15 d) 。 How to correctly use the integration of orifice flowmeter: 1. Guide pressure pipe system filled with cold water for conducting medium pressure, high temperature steam measurement by generally cold water pressure. In pipeline transportation under the condition of steam, not open the valve, pressure valve and balance valve, close the drain valve, directly from the condensation of injecting cold water into tank water injection hole, until full fill. , of course, also can turn off balance valve and pressure valve, a valve open introduced slowly cooling water high temperature steam. This method because of the steam temperature is too high, easy to damage the instrument is generally not used. Special attention should be paid to guide when measuring high temperature steam pressure tube filled with water or high temperature it is forbidden to put into operation. Measure the compressed air, cold water is directly adopted by medium pressure. 2. Vent or drain differential pressure transmitter, pressure pipe filled with water after the, at times the pressure, let indoor differential pressure transmitter to gather a small amount of gas affect conductivity pressure, must be ruled out. Unscrewed the positive and negative pressure, let a bolt drainage at the bottom of the chamber. General new operational instrument without drainage. No leak check guide pressure pipeline system, close all valves, ready to put into operation. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
