MAGSENS - Many asked for a magnetic sensor for permanent installations. This sensor is designed to work with my counters. The MAGSENS is a permanent mount high speed magnetic sensor for high speed pumps like the KERR model T35 pump. Once installed there is little or no maintenance needed. No power is needed for this sensor.
