The Flow Rate Alarm ensures sufficient flows of coolants and lubricants in mobile hydraulic equipment and industrial process control. This variable area flow meter comes equipped with simple on/off logic and a field adjustable alarm setting for simplicity of use. The rugged cast aluminum NEMA type 4X enclosure allows for weather-tight construction in outdoor environments where liquid tight seals are required. Take advantage of the economical protection with the Flow Rate Alarm. It sends alerts of incorrect pneumatic, lubrication or cooling volumes, which protects expensive equipment and reduces production downtime.
Field Adjustable Alarm Setting: Only an allen wrench is required to change the flow alarm setting.
Weather-Tight Construction: Rugged cast aluminum NEMA type 4X enclosure allows installation outdoors and in environments where liquid tight seals are required.
Simple On/Off Logic Positive: alarm points using dry-contact, SPDT switches, reduce the complexity found in standard rotameter OFF/ON/OFF circuits.
Pre-Wired with Cable Disconnect: The standard Hirschmann interconnection provides easy installation and maintenance of the Flow Alarm and the system it is a part of.
Economical Protection: This monitor rapidly pays for itself as it “sounds the alarm” on incorrect pneumatic, lubrication or cooling volumes, protecting expensive equipment and reducing downtime.

Stone crushers in the mining and cement industries grind rocks into smaller particles, using various types of crushers, each employing bearings to support loads and allow for misalignment. Bearing damage can occur from contamination or inadequate lubrication. AW-Lake Flow Rate Alarms are integrated into the crusher lubrication system to monitor oil flow and alert operators of minimal flow conditions, ensuring proper lubrication and preventing premature bearing wear and equipment downtime.
In steel mills, hot oil is sprayed on coil steel to prevent scaling, which is the formation of oxide layers on the steel surface at high temperatures. This protective oil barrier minimizes oxidation, preserving the steel’s quality. Flow meters monitor the hot oil flow rate, ensuring the correct amount is uniformly applied, optimizing protection, and reducing waste. They provide real-time data and alerts for deviations, allowing immediate corrective actions to maintain efficient scaling prevention.
