Abstract: how to ensure the accuracy of gas
turbine meter scale information produced by excellent
flow meter, flow meter manufacturer to offer you the quotation.
Gas turbine flowmeter has high sensitivity, good repeatability, wide range than, high precision, etc. The trade settlement measurement has been widely applied in natural gas, and even as a standard of dissemination of the instrument.
Along with our country and town gas project in full swing.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to ensure the accuracy of gas turbine meter scale article details.
Gas turbine flowmeter has high sensitivity, good repeatability, wide range than, high precision, etc. The trade settlement measurement has been widely applied in natural gas, and even as a standard of dissemination of the instrument.
Along with our country town of fuel gas projects in full swing and the fuel gas trade, the handover measurement requirements unceasing enhancement, the gas turbine flowmeter has gradually become our country town gas is one of the commercial trade and the measuring instrument of choice for handover.
Gas turbine flowmeter is a kind of speed meter, using gas driven flow impeller rotation, the impeller rotating speed is proportional to the fluid volume flow, according to the principle of electromagnetic induction, magnetic sensor using induction out from the synchronous rotation of the impeller is proportional to the fluid volume flow of the pulse signal, the processing volume flow are obtained.
Its measuring accuracy is higher, the precision can reach 1.
Level 0, 1.
Level 5;
Range than wide, is commonly and wide measurement range;
Straight pipe before and after the structure is compact and lightweight, easy maintenance requirements is low, can be used for medium and high voltage measurement.
Turbine meter also has the following disadvantages: there are moving parts, easy to damage, key-module bearing is easy to wear and dirt resistance is poor, higher requirements of the clean degree of the medium, hard to maintain calibration characteristics for a long time, need to check on a regular basis.
The causes of error are: meter itself quality problem, unreasonable design selection, installation does not reach the designated position, in the operation of the improper maintenance, etc.
So how to control the error?
Right to determine the flow meter using places and specifications.
As a result of the existence of turbine flowmeter turbine inertia, frequent fluctuations in flow situation should not be used, otherwise it will reduce the measuring accuracy.
To more accurately estimate the gas peak value and medium pressure situation, correctly determine the specifications of the flowmeter.
Gas turbine meter must be installed before the filter;
Should keep clear of the filter, if found that the filter blocking (
But by filter in and out of the pressure difference) to judge
, should be timely to clean the filter, if not with differential gauge cleaned once a month.
To ensure that the requirements of the straight pipe, especially before the table with reducing or partially open the valve.
Installation, the gasket may not into the pipe, the flow meter visual shall not have obvious deviation to the pipe axis, shall not be installed stress.
When installation to must do all the impurities, clean the pipe to prevent bearings and turbine.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
