FDT7000 Series ultrasonic flow meter is known for easy installation with its snap-clamp on pipe transducer body sensors do not come in contact with the internal liquid. The technology has inherent advantages over alternate ultrasonic devices including: low-cost, easy installation, no pressure head loss, no moving parts to maintain or replace, no fluid compatibility issue, and a wide measuring range that ensures reliable readings from 0.3 to 19 feet/sec (0.1 to 6.0 m/sec). The series is designed to work on PVC, PP and UPVC pipe systems.
The flow meter is equipped with a ground referenced 4 to 20 mA output—the output shares a common ground with the power supply. The output transmits a continuous current output that is proportional to liquid flow rate. The output was scaled at the factory to ensure that the instrument or data acquisition system that is receiving the 4 to 20 mA signal responds properly, it must be spanned identically to the flow.
The 4 to 20 mA output is designed to source current across a loop resistance that is typically located within a data acquisition system or other receiving instrument. The maximum resistance that the flow can accommodate is directly related to the DC power source that is powering the flow meter and the 4 to 20 mA loop.
