Installation and use of glass rotameter scale

Abstract: the installation and use of glass rotameter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Glass rotor flowmeter is now industry, petroleum, chemical industry, environmental protection and other industries on the application of zui to a wide range of a kind of flow meter, flow meter type so much, why glass rotameter zui by, zui popular, because of its features: small pressure loss and sex. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation and use the article details the glass rotameter scale. Glass rotor flowmeter is now industry, petroleum, chemical industry, environmental protection and other industries on the application of zui to a wide range of a kind of flow meter, flow meter type so much, why glass rotameter zui by, zui popular, because of its features: small pressure loss, reliable performance, simple structure, easy installation and use, the price is cheap. Glass rotor flowmeter and small varieties can be divided into many kinds of flowmeter, ordinary glass rotor flowmeter, corrosion resistant glass rotor flowmeter, small flow rate, glass rotor flowmeter selection is a very important step, but choose the product model, how to properly install, how to correctly use, this is an important link. LZB/LZJ series glass rotameter installed 1. Flow meter check carefully before install the float measuring sharp edge ( Reading side) Presence of lesions with guide bar meter should remove float beating padding prevention in the transportation, can check float free sliding on the guide bar. FengHui instrument padding in general is given priority to with packing tape, remove the filler is very convenient. 2. Vertical installation glass rotor flowmeter, flow meter should be installed in vertical position, and have reliable supporting, not any tension and pressure from the pipe. New clothes line, pipe should be rinse after installation flowmeter. By the bottom into the upper flow from flowmeter. FengHui instrument tip: don't hold any flowmeter used in hand! 3. The flow inlet side should be 5 - Ten times the nominal diameter of straight pipe. Beside the flowmeter with bypass line is recommended. 4. By flow cannot be mixed with large particles contamination in the body, can make float stuck or plug flow path, otherwise this kind of need in the upstream flow meters installed filters. 5. Pressure must be stable by flow, fluid pressure instability will cause float moves, not accurate measurements, flowmeter upstream buffer should be set up and the setter. 6. If there are back in the line, to prevent damage to the meter shall be installed after the flowmeter downstream valve one-way check valve. 7. Measured liquid containing bubbles, not if there are any bubbles, must in the upstream flow meter setting vent. LZB/LZJ series glass rotor flowmeter the proper use of 1. Upstream of the valve open flowmeter, slowly open, in order to prevent the float suddenly rushed, damage to the glass tube, and then use downstream of the regulator to adjust flow meter, stop work, should be closed upstream of the valve, then close the valve downstream. FengHui instrument advice: outside the flowmeter bread a circle metal mesh to strengthen security protection. 2. The measurement of body temperature is unfavorable and rapid change, after all is a glass tube, heating and heat bilges cold shrink has may lead to a flow meter glass tube rupture. 3. If there is leakage found in using the flow meter, generally is seal failure, need to change. 4. When cone tube and float dust, should be cleaned in time. 5. Check the error of flowmeter measurement, general flow meter has its own standard, a precision has a tiny error range, once found, beyond the prescribed error should float switch and cone tube, or calibration scale. 6. The flow changes and the fluid temperature and pressure changes, do not agree with the scale on the meter, state of the value is according to the current body and must be amended, Including temperature, pressure, density, etc. ) To get correct flow. 7. Should choose LZB - corrosive fluid ( ) F / LZJ - ( ) F corrosion resistant series flow meter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
