EnchoPod là gì?

EchoPod is our general purpose ultrasonic level transmitter provides continuous level measurement up to 18.0' (5.5m) 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:

Level detection, switch and control functions up to 18.0' (5.5m)

Configuration is fast and easy via WebCal software and USB adapter

Narrow 3" beam width and short 8" dead band optimized for small 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.
