pFlow GF-SH-CL Flow Sensor for High Temperature Water Measurement

Overview

The pFlow GF-SH-CL Flow Sensor is a clip-on ultrasonic instrument engineered specifically for high temperature water measurement, extending pFlow’s compact clamp-on flow sensing platform to fluid temperatures up to 85°C. This makes the GF-SH-CL the natural choice for tracking flow, velocity, and temperature in domestic hot-water loops, solar-thermal returns, and district-heating branches without shutting off or draining the system.

As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC proudly supplies the GF-SH-CL to district heating operators, solar-thermal integrators, and building services contractors across the Sultanate of Oman, Muscat, and the wider GCC. Its 30-second clamp-on setup and zero-downtime installation make it a practical solution for retrofitting temperature monitoring onto existing hot water infrastructure.

Measurement Principle

The pFlow GF-SH-CL uses the ultrasonic transit-time measurement principle to deliver ±3% of full-scale accuracy across a flow velocity range of 0.1 to 16 ft/s (0.03 to 5.0 m/s). Because the transducer clamps onto the pipe exterior rather than penetrating the fluid path, the sensor tolerates the elevated fluid temperatures of hot water systems without any pipe cutting or process interruption during commissioning.

Designed for continuous exposure to fluid temperatures from 0°C to 85°C, the GF-SH-CL is purpose-rated for domestic hot water, solar-thermal, and district-heating applications where standard clamp-on sensors would be pushed beyond their thermal design limits. This gives building services teams a dependable option for monitoring hot water circuits that must remain in continuous operation.

Engineering Design of the pFlow GF-SH-CL

The pFlow GF-SH-CL features an all-in-one transmitter paired with a clamp-on transducer connected via a 5mm black six-core shielded cable with self-locking connectors at a standard 4-meter length. The PC (polycarbonate) engineering plastic body is engineered to be tough and lightweight while carrying an IP54 enclosure rating, supporting reliable operation in mechanical rooms and plant spaces exposed to heat and humidity.

A 1.54-inch LCD color screen with 240×240 resolution and three keypad buttons enable a 30-second field setup, letting installers configure pipe size and material quickly on site. Communication is provided via RS485 with MODBUS protocol alongside a 4–20mA analog output, supporting straightforward integration with building management systems and district heating control platforms.

Key Features

The pFlow GF-SH-CL combines high-temperature tolerance with fast, non-invasive installation. Core capabilities include:

• Fluid temperature rating up to 85°C, purpose-built for hot water and district heating loops.
• Clip-on installation for DN15 to DN50 pipes with no pipe cutting and 30-second setup.
• ±3% of full-scale measurement accuracy across a flow velocity range of 0.03 to 5.0 m/s.
• RS485 with MODBUS protocol and 4–20mA analog output for BMS integration.
• 1.54-inch LCD color display for straightforward field commissioning.
• IP54-rated, tough PC engineering plastic transmitter body for demanding environments.
• Compatible with stainless steel, PVC, copper, and PPR pipe materials.
• Zero downtime installation, allowing continuous operation of hot water systems.

Industrial Applications

The pFlow GF-SH-CL is well suited to domestic hot water systems, solar-thermal installations, and district heating networks across Oman’s commercial and residential building stock. Its high-temperature rating also extends its usefulness to data center HVAC cooling systems with water/glycol mixtures, desalination and reverse osmosis plants, and swimming pool engineering applications.

As the officially authorized partner for pFlow Gentos, Seven Star LLC distributes the GF-SH-CL to building management system integrators, recirculating aquaculture system (RAS) operators, and civil engineering contractors throughout the Sohar and Salalah economic zones and the broader GCC region.
