Level Transmitters : DL24
EchoPod® Multi-Function Ultrasonic Level Transmitter
Application
The general purpose ultrasonic level transmitter provides continuous level measurement up to 9.8' (3m) with a 4-20 mA signal output, and is configured via our free WebCal software. The level sensor has 4 programmable relays with selectable hysteresis and fail-safe logic. The embedded level controller can lower cost by replacing external control hardware. This non-contact liquid level sensor is ideally suited for corrosive, sticky or dirty liquids, and is widely selected for day tank, skid, IBC, sump and process tank level applications.
Features
Switch and control functions with continuous level measurement output up to 9.8' (3m)
Configuration is fast and easy via WebCal software and USB adapter
Narrow 2" beam width and short 4" dead band optimized for day tanks
Four (4) programmable relays rated @ 1A / 60VA for switch, pump or valve control and fail-safety
• 1 pump or valve with 3 alarms
• 2 pumps (lead-lag) with 2 alarms
• 2 pumps (duplexing) with 2 alarms
• 4 independent switch point alarms
PVDF transducer and 6P polycarbonate enclosure for corrosive liquids
Automatic temperature compensation for accurate measurement
The level sensor is configured via our free WebCal PC software and Fob USB adapter. The sensors are offered with and without Fobs. Fobs are universal and can be used to configure any WebCal compatible product. Download your free copy of WebCal in English or Chinese.
