Abstract: differential pressure flowmeter scale with heat and adiabatic guidance information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Key words: differential pressure flowmeter, field instruments, measuring precision, as you know, in some environment condition on site is poor, often to our field instrument measuring line corresponding protection can guarantee the accuracy of measurement.
Interface with everybody here.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is a differential pressure type flowmeter scale guide article details with heat and heat insulation.
Key words: differential pressure flowmeter, field instruments, measuring precision, as you know, in some environment condition on site is poor, often to our field instrument measuring line corresponding protection can guarantee the accuracy of measurement.
And introduce here is the guidance of instrument with heat and adiabatic correct operation.
Take the orifice meter, at the time of some medium at low temperature measurement, on the scene to certain heating measures, the pipeline to ensure the measuring accuracy of differential pressure
transmitter.
Commonly used in industry have steam heat and electricity heating.
When using steam heating, shall meet the following requirements: a, steam trace pipe orifice flowmeter should be used in single loop steam supply and return water, should not be in series connection.
Second, the heavy heating with heat pipe road and measuring line should be close contact, light tracing with heat pipe between the road and measuring line spacing shall be maintained.
Three, orifice flow meter with heat pipe road intercepting should add drainage device.
Four, with the connection of the appropriate welding heat pipe road, fixed they should not be too loose or too tight, should be free.
Five, the liquid
level gauge, the place such as isolator with heat pipe road, union connection should be adopted.
When using electric heating, shall meet the following requirements: one, the electric look and insulation inspection should be done before the installation, insulation resistance should not be less than 1 megohm.
Second, the electricity should be uniform laying, and close to the line, fixed firmly.
Three, laying electricity, should not destroy the insulation layer, core exposed part should be short as far as possible.
Four, instrument box of electric heat pipe (
Board)
Should be installed on the bottom or back wall.
Five, the meter box temperature control device should be installed in the side box walls.
Field measurement of line heating is a very important link, a lot of mistakes because we take it for granted and the action will happen.
So here, hope to give you a summary of the above have the effect of a summary.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
At a time when technology is essential for
mass flow meter, ensuring that it works in a symbiotic way with your human employees is key.
