Universal Flow Monitors, Inc. LP-BBMSE1GLM-4U-32V1.0-A1WR-C-.250 Flow Monitor

The LP-BBMSE1GLM-4U-32V1.0-A1WR-C-.250 Flow Monitor from Universal Flow Monitors, Inc. is a piston-style variable area flow meter and flow switch used to monitor and indicate liquid flow in industrial process systems. It provides local indication and a switch output via a spring-loaded piston design that maintains a low pressure drop, making it suitable for inline installations. With a 4 in port size and inline pipe mounting, this model measures flow up to 300 GPM (series dependent) for water, oils, coolants, chemicals, and other compatible liquids. The fluid viscosity is calibrated at 32 SSU with a specific gravity of 1.0, ensuring accurate readings across typical industrial liquids. It is offered in brass, aluminum, carbon steel, or stainless steel depending on configuration, and features a weatherproof (Type 4) enclosure for use in challenging environments. Upward flow is supported, and the unit is designed for applications including lubrication systems, cooling water circuits, hydraulic systems, and general process equipment where reliable flow indication and flow-loss protection are critical. For reference, common replacements include LL-ABPSB15GH-2U-300V.9-A1WL-4.8D and 02GM-3-600S-A1WR.
