Water meter scale selection of vortex flowmeters scale

Abstract: the water meter scale selection of vortex flowmeters scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. General for water flowmeter selection we will first think of electromagnetic flowmeter and the open channel flow meter, but sometimes medium is very pure and conductivity is very low, or when installing the site do not conform to the requirements of the open channel flow meter installed to do? We have a choice VNL. More flow meter manufacturers choose model price quote you are welcome to inquire, here is water meter scale selection of vortex flowmeters scale article details. General for water flowmeter selection we will first think of electromagnetic flowmeter and the open channel flow meter, but sometimes medium is very pure and conductivity is very low, or when installing the site do not conform to the requirements of the open channel flow meter installed to do? We have a choice & ndash; — VNLUGB worm flowmeters. Vortex flow meter has simple structure, convenient installation and maintenance, small pressure loss, wide range, in addition also has a long service life, stable performance, within the prescribed scope of Reynolds number, the meter coefficient from the fluid temperature, pressure, viscosity and the influence of composition change wait for a characteristic, has been more and more get the favour of people. For water vortex street flowmeter selection must be emphasizing four selection parameters, namely pipe size; The immediate and long-term zui, zui small and common instantaneous flow; The design of the measured medium pressure; The temperature of the measured medium. 1. The choice of caliber caliber of vortex flow sensor is not a must with process pipe diameter, to reasonable choice according to the flow velocity and flow rate. Vortex flow meter caliber main choice must consider that the minimum flow, general measuring water flow velocity limit of 0. 5 m/s, 1/2 - zui to normal flow measurement range Between two thirds. Such as 2. Signal output selection according to the requirement acquisition signal choose different output form, when need to flow accumulation can choose type pulse output, when the need to control can choose simulation ( 4 - 20mADC) Output type. Normally we do 4 - 20 ma signal output to the user. 3. Water meter installation vortex street flowmeter should be installed where the heat insulation, ventilation, easy maintenance, installed in as far as possible away from the vibration source and the strong electromagnetic interference, the vibration of local vibration damping device must be used, reducing pipe affected by vibration. Vortex flowmeter in the pipeline can be horizontal, inclined or vertical installation. Installation position should pay attention to, when the vertical installation, the liquid medium must flow from down to up, shall be installed on the pipe temperature, pressure sensor or flow control valve, temperature, pressure sensor and control valve should be installed downstream of the meter. Vortex street flowmeter must have enough before and after a long straight pipe, the pipe diameter must also and vortex flow transmitter inside diameter is consistent, and pipeline connection of gasket inner diameter slightly larger than the sensor, can not seal protruding into the pipe. 4. Parameter is set the instrument coefficient of flow meter is under the condition of laboratory calibration, the scene, when using instrument coefficient modification. 5. Daily maintenance to ensure the accuracy of the instrument work for a long time, reliability, and avoid the accident shutdown and loss of data, after the flowmeter in operation of the instrument itself and the whole traffic system needs to strengthen daily management and periodic maintenance. 6. The limitations of vortex street flowmeter water due to the vortex street flowmeter is essentially fluid vibration meter, it particularly sensitive to the flow of the external vibration, fluid. Pipeline vibration, the impact of the fluid, and due to the change of fluid pressure, the random fluctuating pressure and so on will be larger influence on instrument measurement. Especially in small flow measurement, transverse lift is small, to small flow detection signal is weak, vulnerable to the pipeline fluid impact vibration noise and the vibration noise. Flow meter manufacturer after 10 years of development, has always been based on the good faith management, to the needs of customers first, with quality assurance. Continuous efforts to develop new technology, improve product performance, with good quality materials, the quality of product is more meticulous, thus obtained the general customers the consistent high praise. All my colleagues look forward to working with you together. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
