MB7851 is a weather-resistant ultrasonic tank-level sensor with 1 mm resolution, 5 m max range, and ~2 Hz read rate. Output is selectable by wiring—RS232 or TTL serial, scaled analog voltage, or analog envelope; supply 3.0–5.5 VDC

Near-field handling is built in: targets closer than 50 mm are reported as 50 mm for predictable readings.

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs). 

The Flood Level Ultrasonic Sensor provides highly accurate non-contact measurement for flood detection and water level monitoring. With 1 mm resolution and models available in 5 m and 10 m max ranges, this sensor is designed for reliable operation in stormwater, municipal, and environmental monitoring applications.

Near-field handling is built in: targets closer than minimum range are reported as minimum range for predictable readings (300mm on 5m models and 500mm on 10m models.)

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs).
