Scale vortex flowmeter in the matters needing attention in the process of installation

Abstract: the vortex flow meter scale matters needing attention in installation process information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex flowmeter is based on the principle of karman vortex closed pipe fluid flow measurement of new type flowmeter. Because of its good adaptability, medium without temperature and pressure compensation directly measuring steam, air, gas, water, the operation condition of the liquid volume flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale matters needing attention in installation process article details. Vortex flowmeter is based on the principle of karman vortex closed pipe fluid flow measurement of new type flowmeter. Medium because of its good adaptability, no compensation can be directly measured temperature and pressure steam, air, gas, water, and the operation condition of the liquid volume flow, temperature, pressure sensor to measure standard conditions and volume flow to mass flow, is the ideal substitute of orifice flowmeter. But many users during the installation process for some improper operation is also easy to make the flow meter in use process produces error and some problems, this article is in view of the installation process to provide some installation matters, hope to be able to make the better use of vortex street flowmeter users. 1, the vortex street flowmeter pipe vibration reduction measures. Sensor to avoid installed in the strong vibration, transverse vibration in particular. If need to install the anti-vibration measures must be taken, respectively at the upstream and downstream of sensor 2 d piping fastening device, and vibration-proof pad. 2, reasonable choice of vortex flowmeters installation site and the environment. To avoid the strong power equipment, high-frequency equipment, strong power switch device; To avoid the influence of high temperature heat source and the radiation source, to avoid strong vibration and strong corrosive environment and so on, at the same time to consider easy installation and maintenance. Vortex street flowmeter sensors on have insulation pipe installation. When measuring high temperature steam, thermal insulation layer zui much can't more than a third of the bracket height. 4, straight pipe upstream and downstream vortex flowmeter must have enough. If the sensor installed upstream of point on the same plane has two 90. Elbow, are: straight pipe upstream & ge; 25 d, the downstream straight pipe & ge; 5 d。 If the sensor installed upstream of point in different plane has two 90. Elbow, are: straight pipe upstream & ge; 40 d, downstream straight pipe & ge; 5 d。 Regulating valve should be installed on the downstream side of the sensor outside 5 d, if must be installed in the upstream of the sensor, the sensor straight pipe upstream should be not less than 50 d, downstream should be not less than 5 d. 5, vortex flow meter installed at upstream and downstream piping should be concentric with sensor, coaxial deviation should be no less than 0. 5DN。 6, vortex flowmeter is installed in horizontal pipe runs flow sensor zui installation method in common use. Measuring gas flow rate, if contain a small amount of fluid in the gas being measured, the sensor should be installed in the pipeline is relatively high. Measurement of liquid flow, if the liquid contains a small amount of gas being measured, the lower part of the sensor should be installed in the pipeline. 7, vortex street flowmeter sensors in a horizontal pipe to the side. Regardless of what kind of flow measurement, the sensor can be in the upper horizontal pipeline, especially the measurement of superheat steam and saturated steam and low temperature liquid, if the condition allows zui to good use side, so the temperature of the fluid have less effect on the amplifier. 8, vortex street flowmeter sensors in vertical pipeline installation. Measuring gas flow rate, the sensor can be installed in vertical pipe runs, flow to the unlimited. If the measured gas containing a small amount of liquid, gas flow should be from the bottom up. Measuring the liquid flow rate, liquid flow shall be from the bottom up: it won't attach additional liquid weight on the probe. 9, vortex street flowmeter sensors in a horizontal pipe of inversion. Generally do not recommend using this installation method. This installation method is not applicable to measure the general gas, superheated steam. Can be used for measurement of saturated steam, high temperature suitable for measuring the liquid or frequent cleaning pipelines. 10, vortex flowmeter, pressure and temperature measuring points of choice. According to the demand of measurement should be near the sensor to measure the pressure and temperature, the pressure measuring point should be 3 - of the downstream of the sensor 5 d, temperature measuring points should be 6 - of the downstream of the sensor More than 8 d place is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.

However, with the increased prevalence of mass flow meter, it has become far more affordable.
