Flocorp PDFlo™ PDSR1 and PDSR2 is a dual hall effect sensor that is compatible with PDFlo Positive Displacement Spur Gear Flow Meters. This microprocessor-based sensor can detect both uni- and bi-directional flow. The sensors’ mode of operation is determined by an output selection switch located inside the housing. The PDSR2 detects the rotation of the flow meter’s gears and emits a frequency signal proportional to flow. The output signal is a square wave pulse which has a duty cycle of approximately 50%.
The signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When a trip occurs, turn off power to the sensor and remove the output load to reset fuse. The PDSR2 is supplied with a sinking (non-powered) output or a sourcing (powered) frequency output.
