How to install the ultrasonic heat meter correctly

Abstract: The information on how to install the ultrasonic heat meter correctly is provided by the excellent flowmeter and flowmeter manufacturer and quotation manufacturer. ■Please flush the pipeline before installation to prevent stones and other debris in the pipeline; ■Please do not turn the electrical part during installation, and do not grab the head part by hand when carrying it; ■Do not pull, rotate or hit the inside of the pipeline during installation Parts, avoid bumping the watch body and. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details on how to install the ultrasonic heat meter correctly. ■Please flush the pipeline before installation to prevent stones and other debris in the pipeline; ■Please do not turn the electrical part during installation, and do not grab the head part by hand when carrying it; ■Do not pull, rotate or hit the inside of the pipeline during installation Parts, avoid bumping the watch body and damage the wires; ■ Do not pull the wires during installation and use to prevent damage; ■ There should be enough maintenance space during installation; ■ Please stay away from AC and high-frequency radiation sources for at least 0.5m to avoid Turn on the high temperature radiation source and avoid direct sunlight; ■ Please do not exceed 2.5MPa during the pressure test to ensure that the flow rate is within the flow range of the heat meter, see the technical parameters for the flow rate range; ■ Installation must follow the direction of the flow indicating arrow on the pipe section; ■ The length of the straight pipe section in front of the water inlet should be 5 times the diameter and the length of the straight pipe section after the water outlet should be 2 times the diameter. To ensure that the water flows from bottom to top; the ambient temperature of the heat meter is greater than 55°℃ or the water temperature in the pipe is greater than 90°When the temperature is ℃, the integrator and the supporting plate should be removed and installed on the wall or other objects with lower temperature; when the heat meter is used as a cooling meter, the integrator and the supporting plate should be removed and installed on the wall or other temperature close to the temperature. On the object at room temperature, and the height of the integrator should be higher than the pipe section to prevent the condensed water from dripping onto the integrator along the wire; Install the red label platinum resistance in the temperature measuring hole of the heat meter; Temperature sensor (platinum resistance) After installation, the lead seal should be sealed; ■The air in the pipeline should be fully emptied before the pressure test after installation; ■If there is no heating in winter, the water in the pipe must be drained to prevent freezing and cracking; ■The pipe flange and Installation of the flange of the heat meter: 1. Reserve the installation position of the heat meter according to the actual size of the heat meter; 2. Put the flanges on both sides of the pipe on the pipe (do not weld); 3. Install the heat meter and the gasket Simply install on the pipe with screws (not too tight); 4. Use an electric welding torch to locate the flange; 5. Remove the heat meter; 6. Weld the pipe flange to prevent water leakage; 7. Install the heat meter; 8. It is strongly recommended that The installation position of the meter body should meet the distance of 2 times the diameter of the pipeline and install the pipeline expansion device at the back, which is convenient for the installation of the heat meter; 9. It is recommended to install the valve in front of the meter, the valve behind the meter, and the filter, which is convenient for maintenance; The heat meter is installed with the corresponding platinum For the resistance mounting head (iron joint), use an electric welding machine to make holes in the return pipe (the meter is installed on the water supply pipe as an example), which is slightly larger than the iron joint, and use an electric welding machine to weld the iron joint on the pipe wall; ■ For DN50, 65 heat meters, install the blue label platinum resistance on the platinum resistance mounting head (iron joint); For heat meters above DN80, you need to install the matching temperature measuring sleeve, and the raw material tape is installed on the platinum resistance mounting head (iron connector), install the blue label platinum resistance in the temperature measuring sleeve; DN50, 65 platinum resistance installation A, red label temperature sensor is installed on the watch, blue label temperature sensor is installed on the back Inside the water thermometer. As shown in Figure 1; B. When connecting the temperature measuring seat, remove the blocking plug first; C. Remove the black on the probe“O”Take out the ring and put it into the deepest part of the platinum resistance mounting hole, then gently install the probe into the temperature measuring seat, and then tighten it by hand. After tightening, you can use a wrench to reinforce it by half a circle. Be careful not to over tighten the wrench to prevent damage to the black“O”ring, causing water leakage; D. All the surplus wires (data wires, temperature measuring wires) are placed in the wire grooves. Make sure there is no redundant wiring outside the wireway. E: The temperature sensor should be reserved for maintenance and cannot face the wall; DN80 platinum resistance installation A, the red label temperature measurement sensor is installed in the water inlet temperature measurement seat, and the small screws on both sides of the bolt are tightened to prevent platinum resistance Sliding down, the blue label temperature measuring sensor is installed in the return water temperature measuring seat, as shown on the right. B. When the temperature measuring sleeve is installed on the iron joint, it must be wrapped with enough raw material tape to prevent water leakage. C. After the temperature measuring sleeve is inserted into the platinum resistance, the M2.5 screws on both sides must be tightened to prevent the platinum resistance from slipping. D. All Yufu connection lines (data line, temperature measurement line) are placed in the wire groove. Make sure there is no redundant wiring outside the wireway. E: The temperature probe should reserve a maintenance position and cannot face the wall; the above is the entire content of this article, you are welcome to inquire about the flowmeter selection and quotation of our factory.
