Greyline Instruments SLT 5.0 Level & Flow Monitor

The Greyline Instruments SLT 5.0 level and flow monitor is a versatile instrument designed 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. The non-contact ultrasonic sensor mounts above the liquid being measured so it will not obstruct the flow nor be prone to fouling.

The SLT 5.0 is easy to set up and operate. Use the built-in 5-button keypad/menu system to input the calibration parameters and the SLT 5.0 will quickly calculate the volume in horizontal round tanks, or flow rate (and total) through any flume or weir. The standard PVC and Teflon sensor is rated for measurement ranges up to 32ft. The SLT 5.0 provides an accuracy up to 0.25% of Range or 2mm (0.08in) whichever is greater.

The SLT 5.0 has an isolated 4-20mA output which can transmit flow data to remote chart recorders or displays. The two control relays (upgradeable to six) are programmable for level/flow alarm, and flow proportionate pulse (for samplers, chlorinators or remote totalizers). An Intrinsic Safety Barrier is optional for sensor and cable installation in hazardous rated locations. The separate, watertight electronics/display enclosure is mounted at a convenient location within 500ft (150m) of the sensor
