Universal Flow Monitors SN-ASB.5GM-3-160V.9-A3WR-RG-PC5-.3D Type 4

Description:

The Universal Flow Monitors SN-ASB.5GM-3-160V.9-A3WR-RG-PC5-.3D is a vane-style variable area flow meter and flow switch used to monitor and indicate low liquid flow rates in industrial process systems. Commonly installed in cooling water systems, lubrication circuits, hydraulic systems, and industrial machinery requiring reliable flow measurement and flow-loss protection. Maintenance teams, OEMs, and system integrators use this flow monitor for replacement, retrofit, and new installations to protect equipment, verify flow conditions, and maintain process efficiency. The unit features a Type 4 weatherproof enclosure with electrical switch contacts rated for 125 VAC and 250 VDC operation. 

Applications:

The Universal Flow Monitors SN-ASB.5GM-3-160V.9-A3WR-RG-PC5-.3D is used to measure the flow of water, oils, coolants, chemicals, and other compatible liquids in industrial piping systems. It is commonly found in pumps, heat exchangers, compressors, machine tools, and process equipment where maintaining adequate flow is critical for safe and efficient operation. The SN series uses a spring-biased swinging vane design that provides immediate response, low pressure drop, and optional switch outputs for alarms or interlocks.
