SLT32 Level & Flow Monitor

Use this versatile instrument to continuously measure, display, transmit and control liquid level in storage tanks or pumping stations, or to monitor and totalize Open Channel Flow through any flume or weir. Mount the non-contacting ultrasonic sensor above the liquid being measured and install the watertight Electronics enclosure nearby. Features a user-friendly keypad calibration system, two digital displays, an isolated 4-20mA output and 3 programmable control relays.

Calibration is easy with the built-in 3 button keypad. The SLT32 offers simple menu selection of measurement units (gallons, liters etc.), calculates volume in horizontal round tanks, or flow rate (and total) through any flume or weir.

For hazardous locations, the ultrasonic sensor is rated Intrinsically Safe with an optional safety barrier. The standard PVC Sensor (optional Teflon) is rated for measurement ranges up to 32 ft/10 m, or use the optional PVC Sensor rated for 50 ft/15.6 m measurement range. Options include 3 additional control relays (6 total) and a built-in 50,000 point Data Logger.
