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. |

Ideal for pump stations, wet wells and tank level control with a non-contacting ultrasonic sensor mounted above the liquid. The new Greyline PSL Level Controller has 6 independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm and echo-loss alarm.
Mount the 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, built-in calibrator to set up measurement range and relay set points. Or use the free "PSL Remote" Windows software to calibrate from your PC by RS232 connection, or through modems over a regular phone line.
PSL Relay/Pump run time data is stored automatically by the instrument. Retrieve reports directly through the PSL display, or through its RS232 output. The PSL Remote Windows software program displays a pump run time graph and will output data to a spreadsheet file or directly to a Microsoft Excel spreadsheet with DDE.
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. |

This new Greyline Transmitter displays, controls and transmits level. Mount the non-contacting 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. All ultrasonic sensors are available with optional intrinsic safety for installation in hazardous rated locations. The LIT25 can also be ordered with gauge-type pressure sensors for special applications. |

Monitor and data log Tank Farm inventory from your PC computer. Install one TFT32 Transmitter at each tank with your choice of Sensors including ultrasonic, pressure, or 4-20mA from existing sensors. You can also include other process variables like flow or pH in the system.
Connect up to 32 TFT32 Transmitters in a network and run Greyline TFS Tank Farm Software to display levels, monitor relay status, and data log tank levels. The system is reliable - TFT32 Transmitters and additional control relays continue to operate even without PC connection. The system allows modem connection to multiple sites by telephone and/or radio modems and can be configured to dial remote sites at specific time intervals.
Greyline TFS software runs in Microsoft Windows 3.1+, Windows 95™ and NT. A new LAN version is available for PC networks allowing multiple users to view and datalog selected tanks/transmitters. |
