Ultrasonic Level


The Greyline LIT25 Level Transmitter displays, controls and transmits level. Mount the noncontacting ultrasonic sensor at the top of your tank, and the compact, watertight electronics/ display enclosure at a convenient location nearby. Operators can calibrate the LIT25 with its 2-button Keypad, without climbing the tank. Use the built-in relay for level control or alarm, the large 4-digit display for local indication, and the isolated 4-20mA output to to transmit level to a PLC.

The standard ultrasonic sensor measures liquid levels up to 32 ft. (10 m), and includes automatic temperature compensation. Choose the optional all-Teflon sensor for chemical compatibility, or one rated to 50 ft (15.6 m) range. The LIT25 can also be ordered with gaugetype pressure sensors for special applications.

Level and Flow Monitoring SLT5.0

Use this versatile instrument to continuously measure, display, transmit and control liquid level in storage tanks and 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, backlit LCD display, an isolated 4-20mA output and 2 programmable control relays.

Calibration is easy with the built-in 5 button keypad. The SLT 5.0 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 and Teflon Sensor is rated for measurement ranges up to 32 ft/10 m, or select optional sensors for flange-mount or applications requiring longer measurement range. Options include 4 additional control relays (6 total) and a built-in 2-million point Data Logger with USB output to Flash memory sticks.

Hybrid pump station level controller PSL5.0

Ideal for sewage pump stations, lift stations, wet wells and tank level control with a non-contacting ultrasonic sensor mounted above the liquid. The new Greyline PSL 5.0 Level Controller has 6 independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm and echo-loss alarm.

Mount the non-contacting, ultrasonic sensor in the tank or wet well and install the watertight electronics in the control room or any location within 500 ft / 150 m. Use the simple menu system and built-in keypad to set up measurement range, relay set points and pump alternation sequence. A relay/pump run time report is updated and stored automatically for viewing on the PSL 5.0 backlit LCD display.

For hazardous locations, the ultrasonic sensor is rated Intrinsically Safe with an optional safety barrier. It 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.
