The installation of vortex flow meter scale pay attention to the point

Abstract: the scale of the vortex flowmeter installation note points information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. VNLUGB vortex flowmeter is produced with the use of fluid through the obstruction stable vortex, two implementation flow generated by measuring the vortex frequency measurement. Vortex flowmeter by vortex flow sensor and flow display instrument of two parts, the display instrument for gm. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale vortex flowmeter installation note points article details. VNLUGB vortex flowmeter is produced with the use of fluid through the obstruction stable vortex, two implementation flow generated by measuring the vortex frequency measurement. Vortex flowmeter by vortex flow sensor and flow display instrument of two parts, the display instrument for common flow display instrument. Flowmeter technology below small make up, to the installation of the flowmeter are introduced for everybody pay attention to the point. 1. Steam flow meter must be installed in a horizontal straight pipe road, if the steam pipe is vertical pipes, the bypass pipe should be set level. Meter inlet side to have straight section (10 ~ 15 d D for pipe diameter) , the export side should be 5 ~ 10 d straight pipe, pipe diameter must be the same as the nominal size of the flowmeter. 2. When actual steam pipe diameter and nominal size of the steam flowmeter is inconsistent, in addition to ensure before the back flow of the length of the straight pipe, the pipe should be installed in the joint of pipe size horn. 3. With flowmeter must steam flowmeter of the flow direction of the arrow on the body in the same direction, at the same time must make indicator when installed in the pipeline, below the dial indicator plane vertical to the ground. 4. For wet saturated steam with high moisture content, flow meter should be installed in the downstream of hydrophobic, in order to discharge liquid fluid. 5. On the meter gauge interface or flow meter on the inlet side of the straight pipe, should install a pressure gauge, in order to adjust the pressure of the flow meter according to pressure value compensation device. 6. Adjust the steam flow meter of pressure compensation device, make practical use of steam pressure and flow meter calibration pressure consistent. After adjustment when open the indicator of protecting cover, screw nut, rotating pipe scale, make the pressure of the dial indicator dividing line and indicator for pressure of scale corresponding dividing line alignment, then nut tighten, then cover the back cover. 7. Steam flow meter before work, must be water injection box filled with damping liquid. Can send the note on the water tank water injection port and port in four bolt, screw down in the mouth with water, water injection to drain out liquid confirm no yellow rust and dirt, will drain bolt tightening. Continue to filling water mouth and confirm there is no gas injection water tank, the water flooding bolt tightening. Injection of damping in the liquid must be fill, otherwise affect the measurement precision and internal parts damaged flowmeter. Damping liquid generally with running water, when the meter when ambient temperature is below freezing or intermittent use, liquid limit, to prevent frostbite, anti-freezing damping liquid using 5% glycol aqueous solution, when to stop using damping liquid should be released. Vortex street flowmeter measurement accuracy reaches 1. Level 0, used to measure liquid, gas, steam medium at low temperature and all kinds of corrosive medium, such as widely used, has a broad development prospects. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
