Introduction Flowline offers several level indication products designed specifically for standard 20-, 30- and 55gallon drums. These level indicators will fit-up directly with standard 3/4” NPT bungs. This family of standard level switch (es) comes in low-level, high-level and multi-level designs, for both low-and highlevel indication. The basic level switch uses an on-board battery supply as a power source. Alarms are available in either a fixed-mount (to the level switch) or a remote-mount design.

Electrical Interface o Typical Current and Voltage Ratings Watts 30 30 30 30 Voltage 240 VAC 120 VAC 120 VDC 24 VDC Amps (resistive) 0.14 A 0.28 A 0.07 A 0.28 A o Note: The ratings above are for resistive loads only. For inductive loads, maximum switch life will be achieved if appropriate arc suppression is used. Operation Alarm box has two LED that indicate when an alarm occurs. The LED’s are for High-Level and LowLevel.
Maintenance Maintenance should consist of inspection to see that the float is free to move and not coated with any substance, which would change its weight or volume significantly. If this occurs, the float should be cleaned. This is easily accomplished without disturbing the installation. In addition, the stem may be wiped down to remove any build-up. The only repair possible in the field is replacement of either the float or stem. Dents or nicks on the float are usually of no consequence to operation.
Cleaning procedure: 1. Power: Make sure that all power to the switch, controller and/or power supply is completely disconnected. 2. Switch removal: If necessary, make sure that the tank is drained well below the switch prior to removal. Carefully, remove the sensor from the installation. 3. Cleaning the switch: Using a soft bristle brush and mild deter-gent, carefully wash the switch. Do not use harsh abrasives such as steel wool or sandpaper, which might damage the surface of the sensor.
