The Flowline EchoPulse LR15 Pulse Radar Level Transmitter provides continuous level measurement up to 98.4ft (30m) with a 4-20 mA signal output, and is configured via its integral push button display module. The non-contact liquid level sensor is intended for petroleum, water, wastewater and diluted chemical storage or process applications in above or below grade tanks of any material. Select this sensor for challenging application conditions with low or non-corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a tank adapter, flange fitting or metal stand-pipe. Offered in three antenna sizes, select the appropriate size based upon the desired beam angle, available mounting port size and process condition. The longer the antenna, the narrower the beam width and stronger the RF signal output for more challenging processes.
The Background: A wastewater facility requires a level transmitter to monitor the level of wastewater pumped into tanks for treatment.
The Problem: The ultrasonic level transmitters previously used were unreliable as effluence in the wastewater would foam as it was pumped into the tanks causing the ultrasonic level transmitters to lose the signal and go into error mode creating the potential for overflow.
The Solution: Flowline's LR15 measures liquid levels using pulse radar which is unaffected by foam or agitation. Although more expensive than ultrasonic level sensors, the LR15 is less expensive than most other radar level transmitters. With a small dead-band and wide process temperature range, the LR15 is ideal for challenging applications with low or non-corrosive media.
