The Rosemount 3051L Level Transmitter is a high-performance device designed for precise level measurement in liquids, utilizing hydrostatic pressure principles. Proper installation is critical to ensure accuracy and longevity. Begin by selecting an appropriate mounting location. Ensure the transmitter is installed in a position where it can directly measure the hydrostatic pressure of the liquid column. Avoid areas with excessive vibration, temperature fluctuations, or exposure to corrosive gases. For flange-mounted installations, verify that the process connection matches the transmitter's flange specifications (e.g., ANSI, DIN). Use compatible gaskets and bolts to secure the flange, ensuring a leak-free seal. For threaded installations, apply thread sealant compatible with the process fluid and tighten according to torque specifications provided in the manual.
Mount the transmitter vertically to prevent measurement errors caused by tilting. When measuring liquid in tanks, position the transmitter below the minimum liquid level to ensure the sensing diaphragm remains submerged. If the tank is pressurized, install a diaphragm seal or isolator to protect the transmitter from overpressure. For open tanks, ensure the low-pressure side (L side) of the transmitter is vented to atmosphere. Electrical connections must comply with local safety standards. Use shielded twisted-pair cables for the 4-20 mA output and HART communication. Connect the cable to the terminal block as per the wiring diagram, ensuring proper grounding to mitigate noise interference. After installation, perform a leak test using inert gas or water at 1.5 times the operating pressure. Finally, power up the transmitter and verify basic functionality using the local display or a HART communicator.
