LEFOO LFT Submersible Liquid Level Transmitter with Digital LCD Display | 4–20 mA Output

LEFOO LFT Submersible Level Transmitter — with Digital LCD Display

Get real-time level readings right at the instrument — no separate display panel required. The LEFOO LFT submersible level transmitter features a built-in green backlit LCD display mounted on the field head, giving operators an instant local readout while simultaneously transmitting a 4–20 mA signal to your PLC, SCADA, or data logger. Drop the stainless steel probe into any tank, borehole, or reservoir and start monitoring immediately.
