How to correctly choose the installation point of the vortex flowmeter

Abstract: The information on how to correctly choose the installation point of the vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. The correct selection of the installation point and the correct installation of the sensor are very important aspects of the precession vortex flowmeter. If the error in the installation process is light, it will affect the measurement accuracy, and the heavy one will affect the service life of the sensor, or even damage the sensor. Consider installation and removal. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to correctly choose the installation point of the vortex flowmeter. The sensor should be installed on pipelines with strong vibration as far as possible. If it is necessary to install it, vibration reduction measures must be adopted. Pipe fastening devices and anti-vibration pads should be installed at 2D upstream and downstream of the sensor. Special attention: the vibration is strong at the outlet of the air compressor, so the sensor cannot be installed, and it should be installed after the air storage tank. Requirements for the external environment 1. The sensor should be avoided to be installed in places with great temperature changes and to be radiated by the equipment. If it must be installed, measures must be taken for heat insulation and ventilation. 2. The sensor should not be installed in an environment containing corrosive gases. If it must be installed, ventilation measures must be taken. 3. It is best to install the sensor indoors. When it must be installed outdoors, measures to prevent moisture and sun must be taken. Pay attention to whether water will flow into the amplifier box along the cable. 4. There must be ample space around where the sensor is installed, and there should be lights and power sockets for installation, wiring and scheduled maintenance. 5. The wiring position of the sensor should be away from electrical noise, such as high-power transformers, motors and power supplies. 6. There should be no radio transceiver near the sensor installation point, otherwise high-frequency noise will interfere with the normal use of the sensor. The installation of the sensor on the horizontal pipeline The installation on the horizontal pipeline is the most common installation method of the flow sensor. When measuring gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed at a higher part of the pipeline.√× When measuring liquid flow, if the measured liquid contains a small amount of gas, the sensor should be installed at the lower part of the pipeline.√× Installation of the sensor in the vertical pipeline When measuring the gas flow, the sensor can be installed on the vertical pipeline, and the flow direction is not limited. If the measured gas contains a small amount of liquid, the gas flow should be from bottom to top. When measuring liquid flow, the flow direction of the liquid should be from bottom to top, so that no extra weight of the liquid is added to the probe. The sensor can be mounted on the side of the horizontal pipe No matter what kind of fluid is being measured, the sensor can be mounted on the side of the horizontal pipe. Especially for measuring superheated steam, saturated steam and low temperature liquid, if conditions permit, it is better to use side loading, so that the temperature of the fluid has less influence on the amplifier. In general, this installation method is not recommended when the sensor is installed upside down in a horizontal pipe. This installation method is not suitable for measuring general gas and superheated steam. It can be used to measure saturated steam, and it is suitable for measuring high temperature liquid or when the pipeline needs to be cleaned frequently. The instrument adopts flange clamping type (also called wafer type, clamping type). Tighten the long bolts and clamp the sensor with two flanges. The concave part of the flange covers the sensor, and the convex part of the flange covers the user tube. The installation steps are as follows: 1. Calculate the installation size first; 2. Saw the pipe orifice plate flow channel to be installed on the sawing machine, and repair the saw edge; 3. Put the flange on the pipe, and then spot weld it after fixing it. Weld the whole circle again to check whether it is in good condition; 4. Repeat the previous step to weld the flange on the other side; 5. Move the pipe with the welded flange to the installation site, install the pipe and the sensor into one, and then install it on the pipeline 6. Check whether all links are in good condition, slowly open the valve, and observe whether there is leakage. Special attention: ①The flow direction of the fluid must be consistent with the flow direction arrow on the sensor body; ②When installing the sensor, during the welding process of the steam flowmeter flange or pipeline, the sensor must not be on the pipeline, so as not to damage the electronic amplifier circuit of the sensor; ③ The flanges on both sides of the sensor must be kept parallel, otherwise it is easy to leak. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
