FLOW ALARMS www.lakemonitors.
NOTE: Installation, operation and cleaning instructions for the basic flow meter cartridge can be found in the first section of this manual. The following instructions are specifically for meters with electrical switches for flow alarms. General Information Lake’s Flow Alarms are typically used to make or break a set of electrical contacts to signal a limit setting. They may be used to turn on a warning light, sound a bell or horn, or even to shut down a process.
The pointer indicates the set point for the alarm switch. In Illustration 1, the switch will be actuated at all flow rates below 4 GPM. To change the set point, simply loosen the switch glide screw one (1) turn and slide the switch to the desired position along the flow rate scale. When the pointer is pointing to the desired flow rate, re-tighten the switch glide screw.
