Installation of vortex flowmeters what are the requirements? Electromagnetic flow meter how much?

Vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid, steam and other media. In order to ensure the accuracy of the meter, vortex street flowmeter installation need in strict accordance with the requirements, the next Beijing tzu chi in kaifeng industrial control instrument co. , LTD. , said the specific installation requirements. Vortex street flowmeter installation requirements: 1, select installation location should 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, the sensor can be installed in the ( Indoor or outdoor) Horizontal, vertical or inclined pipes. But when measuring the liquid, the pipe must be full of liquid, namely: when installed in vertical or inclined pipe, the flow of liquid should flow from bottom to top. 3, sensor installation of straight pipe should be as far as possible with the sensor size ( DN) Consistent. If not consistent, should use slightly larger diameter than the sensor size, and the error to 3% or less is not more than 5 mm. 4, 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 of 25 d, or downstream straight pipe section 5 d or higher. If the sensor installed upstream of point in different plane has two 90. Elbow, are: straight pipe upstream of the 40 d or higher, the downstream straight pipe section 5 d or higher. 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, selection of pressure and temperature measuring points, according to the needs of measurement, to 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 8D。 Superfamily shihua is is a company specializing in the research, development, production and sales all kinds of liquid level, flow control and material level control of high-tech enterprises, the main products: electromagnetic flowmeter, ultrasonic flowmeter, vortex flowmeter, turbine flowmeter, orifice flow meter, etc. , in accordance with the needs of each client product development, we sincerely invite the broad masses of new and old friends to choose products.
