Industrial Vortex Flow Meter RS485 4-20mA Output for Compressed Air Natural Gas and Liquid Flow Measurement DN50

Our flowmeter utilizes advanced DSP (Digital Signal Processing) and a dual-sensor structural design. This technology effectively filters out mechanical vibration interference and electrical noise. The upgraded shock-resistant processor can further ensure stable readings even in complex factory environments. Unlike traditional analog meters, our vortex flow meters provide a clean signal with an accuracy of plus or minus 1.0 percent for liquids and plus or minus 1.5 percent for gas or steam.

Yes.the LUGB series is specifically designed for steam applications with a wide temperature range of -40 degrees c to 250 degrees c (standard) and up to 350 degrees c for high-temperature versions.we provide integrated temperature and pressure compensation modules to calculate mass flow accurately,preventing "Steam loss" Due to density changes.

To maintain a stable Karman vortex street, we recommend a minimum of 10D (upstream) and 5D (downstream) for standard straight pipes. If there are T-sections or valves upstream, the requirement increases to 20D-50D.

We offer full-scale connectivity options: 3-wire Pulse, 2-wire 4-20mA, and digital protocols including RS485 Modbus RTU and HART. The meter can be powered by 24VDC or a built-in 3.6V lithium battery. Our HART-compatible versions allow for remote parameter setting and diagnostics, significantly reducing maintenance time.

Our meters feature a wide turndown ratio of 1:10 to 1:15. For low-flow applications, we use high-sensitivity piezoelectric crystals that can detect vortex frequencies even at low velocities (starting from 0.5m/s for liquids). For very large pipes with low flow, we recommend our Insertion Vortex Flow Meter for more cost-effective and accurate measurement.
