Today, the technical specialist from the manufacturer will introduce to you the following factors that should be taken into consideration when using orifice plate flow meters: 1. When measuring the pressure of a liquid, the installation location of the transmitter should be such that it is protected from liquid impacts (water hammer effect), in order to prevent the sensor from being damaged due to excessive pressure. 2. When making the connections, pass the cable through the waterproof connector (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other substances from seeping into the transmitter housing via the cable. 3. During freezing in winter, pressure anti-freezing measures must be taken for orifice flow meters installed outdoors, to prevent the liquid in the pressure tapping from expanding due to freezing and causing damage to the sensor. 4. Prevent sediment from accumulating inside the conduit; 5. When measuring liquid pressure, the pressure tapping point should be located on the side of the pipeline to avoid the accumulation of sediment. 6. The pressure guide tube should be installed in a location with minimal temperature fluctuations; 7. When measuring gas pressure, the pressure tapping point should be located at the top of the process pipeline, and the transmitter should also be installed above the pipeline, so that any accumulated liquid can easily flow into the pipeline. 8. Prevent the orifice flow meter from coming into contact with corrosive or overheated media; 9. When measuring steam or other high-temperature media, it is necessary to use buffer tubes (coils) or other condensers to prevent the operating temperature of the transmitter from exceeding its limits. Flow metering is one of the components of measurement science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today’s era of energy crises and increasing automation in industrial production, the significance and role of flow meters in the national economy have become even more evident.
