Polysonics DHT-P flow meter
 |
Polysonics DHT‑P is a Hydra ultrasonic flow meter that outputs a 4–20 mA signal and operates on 115 VAC/18 VDC power. Common failure points in this class include degraded piezoelectric transducers, cable insulation breakdown, or drift in the internal calibration due to temperature cycling. Initial checks should verify proper voltage supply to the unit, confirm the 4–20 mA loop integrity with a loop calibrator, and inspect for visible damage or corrosion on the sensor housing and connectors. If the signal is present but inaccurate, perform a zero‑flow calibration using a flow‑free test rig and review any error codes displayed on the meter’s LCD.[oss-gpt-20b] |
