pFlow GF-GH-CL Ultrasonic Flowmeter for Immersion Cooling Systems

Overview

The pFlow GF-GH-CL Ultrasonic Flowmeter is engineered for precise flow measurement in small-diameter pipes ranging from DN15 to DN50, purpose-built to serve the growing demand for accurate coolant flow monitoring in immersion cooling systems. As computing power and chip heat generation continue to rise across cloud computing, AI, and data center infrastructure, the GF-GH-CL provides the real-time flow data needed to ensure efficient circulation and maintain optimal cooling performance in these demanding thermal management environments.

As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC proudly supplies the GF-GH-CL to data center operators, industrial cooling system integrators, and process facilities across the Sultanate of Oman, Muscat, and the wider GCC. Its non-contact clamp-on design and compact footprint make it a practical solution wherever small-diameter coolant lines require dependable, leak-free flow monitoring.

Measurement Principle

The pFlow GF-GH-CL uses the ultrasonic transit-time method combined with high-reliability signal processing circuits to measure flow rates accurately in small-diameter pipes. The instrument achieves ±2% accuracy across a flow velocity range of 0.03m/s to 5.0m/s, with repeatability of 0.4%, giving immersion cooling system operators confidence in the coolant flow data driving their thermal management decisions.

Because the flowmeter’s clamp-on design allows installation without breaking into pipes, it preserves the integrity of the coolant loop in immersion cooling systems, preventing potential leaks and disruptions that could compromise sensitive IT equipment. This non-contact measurement approach is particularly valuable in liquid cooling applications where any breach of the coolant circuit carries significant risk to connected electronics.

Engineering Design of the pFlow GF-GH-CL

The pFlow GF-GH-CL features an integrated external clamping structure for quick and easy installation, with a 1.54-inch LCD color screen (240×240 resolution) that rotates 360° for clear readings from any mounting angle. Three touch keys provide straightforward on-site configuration, while the transmitter and transducer housing use durable PC (polycarbonate) engineering plastic, with the clamp available in either aluminum alloy or polycarbonate material.

The all-in-one transmitter pairs with a clamp-on transducer connected via a 5mm black six-core shielded cable with self-locking connectors at a standard 4-meter length, simplifying cable management in tight data center and equipment cabinet installations. The unit operates on a 10-36VDC power supply and carries an IP54 enclosure rating, with the transmitter rated for -10°C to 50°C and the transducer for 0°C to 85°C, covering the operating range typical of immersion cooling environments.

Key Features

The pFlow GF-GH-CL combines small-pipe precision with robust connectivity for immersion cooling applications. Core capabilities include:

• Small-diameter pipe compatibility from DN15 to DN50 with ±2% measurement accuracy.
• Non-contact clamp-on installation preserving coolant loop integrity and preventing leaks.
• 1.54-inch, 240×240 resolution LCD color screen with 360° rotation for flexible reading angles.
• RS485 communication with MODBUS protocol support alongside 4–20mA analog output.
• Cumulative flow tracking to help identify leaks or inefficiencies in the cooling system.
• Wide temperature and humidity tolerance suited to varying immersion cooling conditions.
• IP54-rated PC engineering plastic enclosure for durability in equipment room environments.
• Compatible with water-based coolants commonly used in immersion cooling systems.

Industrial Applications

The pFlow GF-GH-CL is purpose-built for immersion cooling systems in data centers and high-performance computing facilities across Oman, where precise coolant flow monitoring directly supports IT equipment reliability and thermal management efficiency. Its small pipe-size compatibility also extends its usefulness to agriculture and irrigation systems, water and wastewater management, and HVAC applications requiring compact, accurate flow sensing.
