Ultrasonic Level Sensor: XL-MaxSonar-WRMA1

$115.00

Monitor water or liquid levels in tough outdoor environments. This IP67 weather-resistant ultrasonic distance sensor is the best price/quality ratio we’ve found for level or distance sensing projects.

Description

The XL-MaxSonar-WRMA1 ultrasonic sensor is a “sonar range finder”. It sends a high-frequency sound wave to detect and localize targets. It measures the time it takes for the sound to bounce off the target and back to the sensor to calculate the distance between the sensor and the target.

The XL-MaxSonar-WRMA1 detects the largest signal return in its field of view, and filters out small targets and noise. It self-calibrates automatically. It does not include temperature compensation.

The sensor comes in a compact and robust gray PVC housing. It meets the IP67 water intrusion standard, meaning it can be briefly submerged. The housing matches standard electrical 3/4‑inch PVC pipe fittings. (Ask us if you need a different housing).

Applications

Green Stream uses this sensor for outdoor flood monitoring, tide monitoring, and general water level monitoring. We monitor water levels in lakes, ponds, reservoirs, streams, creeks, rivers, swamps, bays and inlets. We also monitor flood-prone dry areas - roadways, intersections, parking lots or dry creek beds.

Other applications include

  • Treatment pond or ditch levels

  • Tank or bin level

  • Proximity (robotics)

  • Large object detection

Features

  • Small and lightweight

  • Easy to use

  • Non-contact

  • Weather-resistant, IP67

  • Low power consumption

  • Continuous, reliable, stable operation

  • Narrow beam, long range

  • Cone focuses beam for greater accuracy

  • Reports distance to target, with built-in noise tolerance and clutter rejection

  • Automatic calibration: voltage, humidity, ambient noise

  • Standard ¾ inch PVC pipe electrical fitting

Technical specifications

  • Resolution: 1 cm

  • Maximum Range: 1 to 24.5 feet (25 to 750 cm) as reported by manufacturer

  • Optimal Range: 2-20 feet (60 to 600 cm) as tested in field conditions by Green Stream

  • Beam: 12 inches diameter (30 cm)

  • Power: 3.0-5.5V

  • Current: 3.4mA

  • Operates at 42KHz

  • Outputs: Serial (RS232), Analog Voltage, and Analog Envelope 

  • RS232/TTL Serial

  • Read/refresh rate: 10Hz

  • Rating: IP67

  • Operational temperature: -40F to +160F (-40C to +70C)

  • 200,000 hours MTBF

  • RoHS compliant

Dimensions

Length: 2.8 in (71.09mm)

Width:  1.73 in (43.84mm)

Weight: 1.75 oz (49.66g)
