Vortex flow meter scale installation requirements

Abstract: the scale vortex flowmeter installation using the information required to be made by the excellent flow meter, flow meter production factory to provide you with quotation. Vortex street flowmeter installation requirements 1, the choice of reasonable installation location to avoid 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 installation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale vortex flowmeter article details installation requirements. Vortex street flowmeter installation requirements 1, the choice of reasonable installation location to avoid 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. 2, upstream and downstream straight pipe 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. 3, pipeline 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. 4, are installed in horizontal pipe runs zui vortex flowmeter 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. Upstream and downstream piping should be installation points and the sensor concentric, coaxial deviation should be no less than 0. 5DN。 5, the installation of sensors in a vertical pipe. 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. 6, selection of pressure and temperature measuring points. 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 8 d7, 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, 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. When measuring high temperature steam, thermal insulation layer zui much can't more than a third of the bracket height. Above is the two-phase vortex street flowmeter to share the content of the above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
