pFlow F5 Ultrasonic Flowmeter for Chilled Water

Name: pFlow F5 Ultrasonic Flowmeter for Chilled Water – Datasheet
Brand: pFlow

Description

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

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.

Why Choose Seven Star LLC for Chilled Water Metering

District cooling and central HVAC operators in Oman frequently need chilled water metering that supports tenant billing as well as engineering data, and getting the F5’s cloud billing configuration wrong at commissioning can mean re-visiting every meter on a project after handover. Seven Star LLC’s team works with facilities management contractors to confirm GENTOS iCloud billing setup and Modbus/WiFi integration requirements before the F5 units ship, so the metering and billing system goes live correctly the first time.

As the authorized regional partner for pFlow Gentos, we also coordinate multi-unit orders for district cooling plants and commercial towers standardizing chilled water metering across several risers or plant rooms in Muscat and the wider GCC.

About brand

Clamp-on ultrasonic flow measurement is what pFlow does. The sensors strap to the outside of the pipe and measure liquid flow by transit time, so the line is not cut and nothing touches the fluid. The brand comes from Gentos, an instrument maker focused on ultrasonic flowmeters, flow sensors and heat and cooling energy meters.

Seven Star LLC is the pFlow agency for Oman and the GCC, listing pFlow ultrasonic flowmeters in fixed, portable and LoRaWAN versions, BTU meters and LoRaWAN flow control valves.

pFlow flowmeter families

Most of the listed models are compact clamp-on sensors grouped by pipe size and duty. The GF family (GFCL, GFR, GF-S-CL, GF-SH-CL for hot water and GF-GH-CL for immersion cooling) and the MF micro flowmeters (MFR, MFCL) serve cooling and process loops on small and medium pipes. The MP series are plug-and-play flow sensors, including the MP801 and a LoRaWAN version. The D116-BTU is a wall-mounted ultrasonic BTU meter, the P116 a portable flowmeter for surveys, and the F8 a fixed meter used in aquaculture. Gentos also builds the F3 series clip-on flowmeters, including a panel-mount version. The VC200-R is a LoRaWAN ball valve that works as a flow switch.

Where pFlow meters are used

The manufacturer documents use in liquid cooling for data centers and semiconductor plants, chilled and hot water metering in central air conditioning, water supply networks and irrigation, aquaculture, and utility lines in petrochemical and power plants.

Ordering a pFlow ultrasonic flowmeter: what we need

Clamp-on meters are selected from pipe data. Send the pipe outside diameter, wall thickness and material, any liner, the liquid and its temperature, the expected flow span and the straight pipe length available. Add the output you need (4-20 mA, pulse, Modbus, LoRaWAN) and the supply voltage. For BTU meters include the supply and return temperature span.
