Installation and wiring method of gas turbine meter scale

Abstract: the gas turbine meter scale installation and wiring method of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas turbine flowmeter is mainly used in industrial pipeline in the air, nitrogen, oxygen, hydrogen, methane gas, natural gas, steam medium such as fluid flow measurement. When the working condition of the measurement volume flow is almost not affected by parameters such as fluid density, pressure, temperature, viscosity of shadows. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a gas turbine meter scale installation and wiring method of the article details. Gas turbine flowmeter is mainly used in industrial pipeline in the air, nitrogen, oxygen, hydrogen, methane gas, natural gas, steam medium such as fluid flow measurement. When the working condition of the measurement volume flow is almost not affected by fluid density, the influence of the parameters such as pressure, temperature, viscosity. Gas turbine flowmeter installation method 1, flow meter before installation, pipeline purging, and in case of residual iron affect the normal operation of flowmeter. 2, before the installation, the use of tiny air blows the turbine, the turbine can flexible rotation, no random noise, count rotation is normal, uninterrupted card lag phenomenon, the flowmeter can be used to install. 3, flowmeter in the middle of the flange and pipe flanges to add sealing washer. Before 4, gas turbine flowmeter should be equipped with filters, temperament is dirtier occasions should add oil filter, it is forbidden to filter and flowmeter directly connected. 5, before and after installation shall be added by the valve. 6, flange joint pipe Canon there should be no protrusions. 7 when installation, gas turbine flowmeter, it is strictly prohibited in the import and export directly to where the flange welding, so as not to burn out flowmeter internal parts. 8, flow meter should be installed in the maintenance, without strong electromagnetic interference and mechanical vibration and thermal radiation effects. 9, should not be installed with frequent interruptions in the flow, and have a strong pulsating flow or pressure pulsation occasions; 10, flow meter outdoor installation, should be the upper cover, to prevent rain water immersion and strong sunlight affect the service life of the meter. 11, flow meter can be installed in horizontal or vertical, the fluid flow direction should be consistent with the direction of the logo on the shell, the vertical pipe installation, the flow direction must be top down out, should guarantee the upstream of the flow meter is not less than 10 dn straight pipe, after the table is not less than 5 dn straight pipe. 12, in order not to affect the normal fluid conveying, must close the by-pass pipe valve when normal use. Gas turbine flowmeter using requirements 1, in the low pressure table zui pressure leak detection: & le; 1. 0 mpa, temperature pressure compensation type leakage pressure no more than three times the upper limit value of the pressure sensor. High pressure case according to the rated flow of 1. 2 times the pressure leak detection. 2, after installation leak test and shall comply with the following provisions: (install and use 1) Turn off gas valve and the inlet valve. （ 2) Slightly open vent valve, and then slowly open the inlet valve, make the table start slowly, then slowly open the vent valve, make the reach normal operation state, to prevent sudden start, damage to the core. （ 3) At the time of stopping air, need to close the vent valve, then close the inlet valve, each time you start all should abide by the rules. 3, gas turbine flowmeter installation use, not to touch the bolt, screw, nut fasteners, such as to avoid danger such as leakage, damage. 5, flow meter movement ( Temperament is clean) Should be once every six months for cleaning maintenance; （ Temperament is a dirty) Should be for cleaning maintenance once a month. 6, if the movement after breakdown maintenance, to be put into use, the need to press zui pressure seal test first. Gas turbine meter connection method 1, the basic gas turbine flowmeter: V + red line, V - green line for power , yellow line for line, wire for the shielded wire. 2, current output type gas turbine meter wiring: V + red line, V - green line for power Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
