18620 Union Butterfly Valve Industrial Water Treatment PVC 150PSI Quick-Actuating Valve

1. Non-Invasive Flow Measurement Solution​

The GF Signet 18620 Proline is a clamp-on ultrasonic flow transmitter engineered for accurate liquid measurement in water/wastewater, HVAC, and industrial processes where pipe modification is impractical. Featuring ​dual-path transit-time technology, this device delivers ​​±1% accuracy​ across ​DN50–DN3000 pipe sizes​ (2"–120") with ​​≤100ms response time. Its ​IP68-rated aluminum housing​ operates across ​​-40°C to +70°C​ while resisting submersion (3m depth) and harsh environments. The transmitter incorporates ​auto-pairing sensors​ with ​​±1° beam alignment​ and ​dynamic gas bubble compensation. Certified for ​ATEX Zone 2/22, it supports ​4-20mA + HART/Pulse outputs​ and ​SIL 2 compliance. Integrated ​Heartbeat Technology®​ enables automated verification and predictive diagnostics for scaling/coating detection without process interruption. Designed for large-diameter pipes, this system provides bidirectional flow measurement with ​ultrasonic wall thickness monitoring​ and ​energy calculation​ capabilities for HVAC/chiller applications.

​2. Critical Applications & Technical Advantages​

This transmitter excels in challenging scenarios:

​Water Treatment: Raw water intake monitoring (0.1–12 m/s)

​District Heating: Energy measurement with temperature inputs

​HVAC Systems: Chilled water flow verification

​Chemical Processing: Corrosive liquid transfer lines

​Power Plants: Cooling tower make-up water tracking
Key advantages include ​no pipe cutting or process downtime​ during installation, ​bubble-tolerant measurement​ (±2% accuracy at ≤10% gas fraction), and ​auto-fluid calibration​ for varying liquids. Its IP68 rating withstands flooded vaults, while the dual-path ultrasonic technology maintains accuracy in partially filled pipes. SIL 2 certification supports safety functions like overfill prevention, and Heartbeat Technology® provides predictive alerts for sensor degradation or wall thinning (>0.5mm/year). The system's <5W power consumption enables solar-powered operation in remote locations with 10-year battery backup option.
