Abstract: the integration of orifice meter scale instructions information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
This company produces the integration of orifice meter is the standard orifice plate with multiple parameter differential pressure transmitter
, temperature transmitter and pressure transmitter of high contrast range pressure flow device, can measure the rate of flow of gas, steam, liquid and gas, a wide range of applications.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the integration of orifice meter scale instructions article details.
This company produces the integration of orifice meter is the standard orifice plate with multiple parameter differential pressure transmitter, temperature transmitter and pressure transmitter of high contrast range pressure flow device, can measure the rate of flow of gas, steam, liquid and gas, widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement.
The following method of use: 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 flowmeter
, 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 filled.
Can also close the balance valve and pressure valve, a valve opens slowly introducing steam cooling water.
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.
Adjustment pressure transmitter zero migration, due to guide water column pressure tube to produce an additional pressure, the pressure display should have additional readings, need for the additional pressure zero, called zero migration.
Electromagnetic flowmeter detailed practice: a valve closed, open the pressure valve, connected to the power supply.
Open the pressure transmitter shell, migration of regulating screw, make the pressure display, the output is zero.
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, can be put into operation.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
have manifold mass flow meter effects, ranging from digital fork density meter to v shape coriolis mass flow meter.
