Product Introduction
GFR ultrasonic flow meters can be quickly installed on DN15-32 stainless steel, copper, PVC or PPR pipes within 1 minute. Their transit time sensor provides ±2% accuracy in the range of 0.03-5 m/s and can be installed on pipes of 18-63 mm without interrupting flow-making them ideal for liquid cooling systems.
- Easy to install,without break pipe
- Easily clip on
- LCD color display
- Liquid Cooling system
- Process industries (chemical, pharmaceutical, food and beverage)
- Energy management and environmental monitoring
- Agriculture and irrigation systems
- Research and development
- Commercial
- Industrial maintenance and troubleshooting
- Carbon footprint, carbon audit, carbon assessment, carbon neutrality, and carbon trading etc.

FAQ
Q: Are you a trading company or a factory?
A: We have been focusing on ultrasonic flowmeters for 32 years and we are a well-known manufacturer integrating R&D and factory.
Q: Does installing the GFR require shutting down the liquid-cooling loop or cutting pipes?
A: No-its clamp-on transducers mount in minutes without breaking the pipe or stopping flow, so servers stay online.
Q: Which pipe materials and sizes can the GFR handle?
A: It fits DN15–DN50 stainless-steel, copper, PVC or PPR pipes; Class-A/B clamps cover OD 18–64 mm with no hardware changes.
Q: How accurate is the GFR in small cooling lines?
A: Factory calibration gives ±2 % of reading from 0.3–5 m/s (0.03 m/s minimum) and repeatability of 0.4 %.
Q: How is the meter powered and how can I access its data?
A: 10–36 VDC supply feeds the unit; data leaves via RS485-Modbus or LoRaWAN (22 dBm, region-selectable) for direct BMS or cloud integration.
