Vortex flowmeter of the very wide range of applications, can be widely used in large, medium and small pipe to the drainage, industrial recycling, sewage treatment, oil and chemical reagents and compressed air, saturated and superheated steam, gas and various medium flow measurement is a very high price of the flow meter.

Vortex flowmeter precautions:

1, a reasonable choice of the installation place and environment. Installation of vortex flowmeter, it is necessary to pay attention to avoid the strong electricity equipment, high-frequency equipment and strong power switch equipment; to avoid the high temperature heat source and radiation source the impact of vortex flowmeter, and try to avoid the strong vibration place and strong corrosive environment, such as, at the same time, to consider the installation and the maintenance are convenient.

2, the sensor in the horizontal pipe side of the. Whether measuring what is fluid, the sensor can be installed in horizontal pipe side, especially the measurement of superheated steam, saturated steam and low temperature liquid, if conditions allow the best side mounted, so that the fluid temperature of amplifier has little effect.

3, the sensor in the horizontal pipe of the flip. This installation method is not recommended for general use. This method does not apply to the measurement of general gas, superheated steam. Can be used to measure saturated steam, suitable for measuring high temperature liquid or need to regularly wash the pipe.

4, vortex flowmeter sensor in insulation layer of pipeline installation should pay attention to the measurement of high temperature steam, heat preservation layer up to not more than one-third of the bracket height.

5, the installation point downstream piping should be concentric and sensor, the coaxial deviation should be less than 0.5DN.

6, for the vibration of the installation environment can not be avoided, the pipe is required to take measures. The vortex flow meter installed in the pipeline to avoid strong vibration, especially the transverse vibration. If you have to install, you must take measures to reduce the vibration of the sensor on the lower reaches of the 2D pipe is set respectively, and the anti vibration pad.

7, the upper and lower reaches of the river must have enough straight section. Theory, if the sensor mounting point on the upstream of the second 90 degree bend in the same plane, upstream straight pipe is more than or equal to 25d, downstream straight pipe section is equal to or more than 5D; if the vortex street flowmeter sensor installed upstream of the point in different planes with two 90 degree elbow, then upstream straight pipe is larger than or equal to that of the 40d downstream straight pipe section is equal to or more than 5D; in addition, regulating valve should arranged outside the flow sensor downstream 5D, if it must be installed upstream of the sensor, sensor upstream straight pipe section should not be less than the 50D downstream should be not less than 5D.

8 in horizontal pipe is the most commonly used in the installation of flow sensor. Measurement of gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed in the pipeline is high; and measuring the flow of liquids, if the measured liquid containing a small amount of gas, the sensor should be installed in the pipeline in the lower elevations.

9 and for split type vortex flowmeter, and selection of pressure and temperature measuring point should be according to the need of measurement, the measuring point should be at the downstream of the sensor 3-5D, temperature measurement points should be in the downstream of the sensor 6-8D. We generally recommend customers use with temperature and pressure compensation function of integrated vortex flowmeter, the intelligent flowmeter has a set of temperature sensors, pressure sensors and flow sensors in one can improve measurement accuracy of flow meter, and can in the instrument itself LCD head synchronous display value of the temperature and pressure of the medium in the pipeline, the most important is avoid also re established the trouble of the construction of the temperature measuring point and measuring point.

Install the sensor 10, vortex flowmeter in vertical pipeline. When measuring the gas flow, the flow meter sensor can be installed in the vertical pipe, the flow direction is not limited. If there is a small amount of liquid in the gas flow, the flow of the gas should be up to the next. When measuring liquid flow, the flow direction of the liquid should be up, so that the liquid will not be added to the probe.
