Electromagnetic flowmeters can be used to measure the flow rate of ordinary conductive liquids, as well as highly corrosive liquids such as strong acids and strong bases. When using them, it is necessary to select an appropriate protection rating based on the actual conditions. So what are these rating standards? 1. IP65: The sensor housing of the electromagnetic flowmeter allows water to be sprayed at it from any direction using a faucet; the spraying pressure is 30 Kpa, the flow rate is 12.5 L/S, and the distance is 3 meters. 2, IP67: The sensor of the electromagnetic flowmeter can be immersed in water for a short period of time. 3. IP68: It is suitable for long-term operation in water or underground under certain pressure; in such cases, the sensor and the display unit of the electromagnetic flowmeter are separated, resulting in a split-type electromagnetic flowmeter. It is important to emphasize the protection rating requirements for electromagnetic flowmeters. In general, the protection rating of an electromagnetic flowmeter should be chosen based on actual conditions. If the sensor is to be installed below the ground level and is frequently exposed to water, an IP68 rating is appropriate; if it is installed above the ground level, IP65 or IP67 ratings are suitable. In any case, the display part of the electromagnetic flowmeter must not be exposed to water or allowed to get wet, as this can cause damage to the device. Insertion-type electromagnetic flowmeters are primarily used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. 1. Installation method:. 1. Insert it along the central axis of the pipeline under test; 2. Insert it at a distance of 0.25D from the inner wall of the pipeline. II. Installation requirements:. 1. Remove welding slag and burrs from the mounting base of the pipe to be tested. 2. Close the upstream flow control valve or use low-pressure water supply. 3. Install the DN50 ball valve on the electromagnetic flowmeter’s mounting base, making sure that the long cavity of the ball valve faces upward. Check whether the ball valve can be fully opened and closed. Install the compression thread seat, compression nut, and rubber seal ring on the ball valve. Loosen the positioning nut, and insert the sensor rod through the ball valve into the pipe to be tested; also ensure that the direction indicator on the sensor aligns with the flow direction of the fluid. The intelligent electromagnetic flowmeter is equipped with a backlit, wide-temperature range Chinese LCD display that is fully functional and practical. It offers an intuitive display and easy operation, thereby reducing the inconvenience associated with the English menus found in other electromagnetic flowmeters. Additionally, we have designed a 4-6 multi-electrode structure that further enhances measurement accuracy; moreover, there is no need for a ground ring at any time, which reduces the size of the instrument as well as the complexities related to installation and maintenance. 1. Select the appropriate pump based on the pipe diameter and flow rate for conducting the testing. 2. If the system uses an electromagnetic flowmeter powered by compressed air, start the air compressor to achieve the pressure required by the system, so as to ensure rapid switching of the commutator and proper operation of the clamp. 3. After the flow meter has been properly installed and connected, it should be powered on and preheated for about 30 minutes in accordance with the requirements of the calibration procedures. 4. If a high-level tank is used as the water source, it is necessary to check whether an overflow signal appears from the pressure stabilizing tower. Before conducting formal tests, the testing medium should be circulated through the pipeline system for a certain period of time, in accordance with the requirements of the calibration procedures; at the same time, it is important to check for any leaks at the various sealing points in the pipelines. 5. Before starting the formal calibration, the calibration medium should be filled into the sensor of the flow meter to be tested, after which the downstream valve should be closed for zero-point adjustment. 6. At the start of testing, the valve at the front end of the pipeline should be opened first, followed by slowly opening the valve behind the flow meter being tested in order to adjust the flow rate at the testing point.
