pFlow F5 Ultrasonic Flowmeter for Chilled Water

Overview

The pFlow F5 Ultrasonic Flowmeter is a stationary, smart, clamp-on instrument engineered for precise flow measurement in chilled water and HVAC circuits. Adopting the transit-time measurement principle combined with advanced ARM.FPGA technology and low-voltage pulse transmission, the F5 delivers accurate flow data with ±1.0% error margin, while its built-in GENTOS iCloud energy efficiency monitoring function gives facility engineers strong billing and internet-connected reporting capability.

As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC proudly supplies the F5 to district cooling operators, commercial HVAC contractors, and municipal water utilities across the Sultanate of Oman, Muscat, and the wider GCC. Its combination of high measurement accuracy and cloud-based billing functionality makes it a strong fit for both technical monitoring and commercial cost allocation in chilled water networks.

Measurement Principle

The pFlow F5 uses the ultrasonic transit-time method with clamp-on transducers installed on the outside of the pipeline, avoiding any contact with the fluid medium. Because the transducers are external, the meter can be installed without shutting down the chilled water system, and there is no pressure drop or obstruction introduced into the flow path—an important consideration for continuously operating HVAC and cooling loops.

Combining ARM.FPGA processing with a proprietary flow algorithm, the F5 measures flow velocities up to 5.0 m/s with high accuracy and repeatability. Automatic offline correction and extensive data storage ensure that measurement quality remains consistent even through power interruptions or variable chilled water flow conditions typical of HVAC systems responding to changing cooling loads.

Engineering Design of the pFlow F5

The pFlow F5 uses a touch keypad for fast and easy programming, with menu selection of pipe diameter, pipe material, liquid type, and measurement units such as gallons or liters. Settings and totalizer values are retained during power interruptions, ensuring continuity of billing and consumption records even after unexpected outages.

The instrument provides daily, monthly, and yearly totalization alongside instantaneous flow rate, volume total, run hours, and diagnostic information, all accessible via optional Modbus RTU or WiFi communications. The built-in WiFi communication module connects to the internet through WLAN, integrating seamlessly into automatic control systems for remote monitoring and management. Through the GENTOS iCloud server, F5 uploads flow data to the cloud, allowing users to view data and reports via mobile phone or PC anytime, anywhere, with an optional billing system featuring independent background management.

Key Features

The pFlow F5 combines precision chilled water measurement with cloud-connected billing capability. Core capabilities include:

• ARM.FPGA technology and low-voltage pulse transmission delivering ±1.0% measurement accuracy.
• Non-invasive clamp-on installation with no pipe cutting, pressure drop, or system shutdown.
• Built-in WiFi communication with GENTOS iCloud energy efficiency monitoring.
• Optional billing system with independent background management for cost allocation.
• Daily, monthly, and yearly totalization with extensive data storage and automatic offline correction.
• Touch keypad programming for fast configuration of pipe diameter, material, and units.
• Multiple output modes including 4–20mA, frequency signals, RS485, and optional WiFi.
• Suitable for a wide range of water types including deionized, cooling, drinking, and industrial water.

Industrial Applications

The pFlow F5 is well suited to chilled water metering, HVAC system monitoring, and municipal water supply applications across Oman’s commercial and infrastructure sectors. District cooling plants and central air-conditioning systems rely on the F5’s high accuracy and cloud connectivity to track chilled water consumption for both technical monitoring and tenant billing purposes.

As the officially authorized partner for pFlow Gentos, Seven Star LLC distributes the F5 to water utilities, sewage treatment operators, and industrial water processors throughout the Sohar and Salalah economic zones and the broader GCC region. Its versatility across water supply, agriculture, chemical, and food and pharmaceutical applications makes it a practical choice for facilities managing diverse fluid metering requirements.
