ULTRASONIC FINDER WATER LEVEL MONITORING

This Ultrasonic Finder sensors uses the latest ultrasonic distance measuring technology for accurate
non-contact water level monitoring. The sensors contain a rugged
transducer in a stainless steel sealed housing for long life and provides an industry standard 4-20 MA output.
There are three ranges available including 3 ft, 12 ft, and 48 ft to meet a wide variety of applications.The unique 3
ft range sensor is ideal for measuring flow in small flumes and weirs. The 12 ft and 48 ft ranges are best for
measuring river, lake and tank levels and for measuring open channel flow in larger flumes. Installation is simple
and requires no programming or calibration. No maintenance is required.

OPERATION:
This Ultrasonic Finder use ultrasonic sound waves to determine the distance from the face of the sensor
to the surface of the water by timing how long it takes the signal to return. An internal temperature
sensor automatically compensates for the temperature related variation in the speed of sound and a 15-
second averaging time reduces the affects of turbulence in the water. Note that the sensor must be
powered for 15 seconds for the output to stabilize.
