A
Single flange pressure transmitter is a specialized industrial instrument designed to measure pressure or liquid level in tanks, vessels, or pipelines by integrating a pressure sensor with a flange mounting mechanism. This design simplifies installation and enhances reliability, making it a preferred choice for applications where direct contact with the process medium is required.
Design and Functionality
The
Single flange pressure transmitter features a pressure-sensing element （e.g., a diaphragm or piezoelectric sensor） mounted on a flange, which is bolted directly to the process vessel or pipe. The flange serves as both a mechanical connection and a process seal, isolating the sensor from the environment while allowing it to detect the pressure of the contained fluid. The sensor converts the applied pressure into an electrical signal, typically 4-20 mA or a digital output like HART, which is then transmitted to a control system or display for monitoring and automation.
Key Advantages
Simplified Installation: The flange mounting eliminates the need for complex piping or impulse lines, reducing installation time and costs.
Direct Medium Contact: Ideal for applications requiring accurate measurement of liquid or gas pressure without the signal loss associated with remote seals.
Robust Construction: Built with corrosion-resistant materials （e.g., stainless steel, Hastelloy）, it withstands harsh chemicals, high temperatures, and abrasive media.
Versatility: Suitable for level measurement in open or pressurized tanks by converting hydrostatic pressure into liquid height data.
Low Maintenance: The sealed design minimizes clogging and leakage risks, ensuring long-term reliability.
Applications
Single flange pressure transmitters are widely used in industries such as chemical processing, oil and gas, water treatment, and food and beverage. Common applications include monitoring boiler drum levels, measuring reactor pressures, and controlling storage tank inventories.
In summary, the
Single flange pressure transmitter offers a compact, efficient, and accurate solution for pressure and level measurement, combining ease of use with durability in demanding industrial environments.
