Endress+Hauser FMU40-ANB2A4 | Prosonic M Ultrasonic Level Transmitter, 2x 4-20mA, 100-230V AC
Endress+Hauser FMU40-ANB2A4 Prosonic M ultrasonic level transmitter. Measures up to 15m liquid / 40m solid, 2x 4-20mA, 2 relays, 100-230V AC, IP66, for tanks & open channels.

Product Overview

The Endress+Hauser FMU40-ANB2A4​ is a micromotion ultrasonic level transmitter​ from the Prosonic M FMU40 series, designed for continuous, non-contact level measurement of liquids and bulk solids​ in tanks, open channels, and silos. It features two 4-20mA outputs, two relay contacts, and a 100-230V AC power supply. The transmitter can be paired with a wide range of Endress+Hauser ultrasonic sensors (FDU90/FDU91/FDU92/FDU93 series) for measuring ranges up to 15 m on liquids​ and 40 m on solids.

Key Features

  • Dual Channel / Dual Output:​ Two independently configurable 4-20mA outputs allow simultaneous level + temperature or level + calculated flow (weir/flume) reporting.
  • Pump & Alarm Control:​ Two integrated SPDT relays enable direct control of fill/drain pumps or high/low level alarms without external interposing relays.
  • Advanced Echo Processing:​ Prosonic patented algorithms suppress false echoes from tank obstructions, agitators, or surface turbulence.
  • Weir & Flume Calculation:​ Built-in math function computes flow rate from level in open channel installations (Parshall flume, Palmer-Bowlus, etc.).

Applications

  • Open Channel Flow:​ Level + flow measurement in wastewater flumes and weirs for discharge monitoring.
  • Storage Tank Level:​ Non-contact liquid level in chemical storage, water, and wastewater tanks (above ground / underground with pit sensor).
  • Bulk Solid Silos:​ Level monitoring in grain, plastic pellet, or powder silos (with appropriate FDUsolid sensor).
  • Sumps & Wet Wells:​ Pump control based on level setpoints with alternating pump logic.
Note: For panel-mount version, see FMU30 series. Sensor (FDU9x) must be ordered separately — the FMU40 is the transmitter/electronics only.
