pFlow MFR Micro Flowmeter for Data Center Cooling

Name: pFlow MFR Micro Flowmeter for Data Center Cooling
Brand: pFlow

Description

Overview

The pFlow MFR Micro Flowmeter is a compact, clip-on ultrasonic flow meter designed for precise flow measurement in small pipes, purpose-built for data center cooling infrastructure. It uses LoRa communication for wireless data transmission, making it ideal for IoT applications where monitoring points are distributed across server rooms, chiller plants, and cooling towers without the cost of running dedicated wiring.

As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC proudly supplies the MFR to data center operators, colocation facility managers, and IT infrastructure teams across the Sultanate of Oman, Muscat, and the wider GCC. Its compact DN10 form factor and wireless connectivity make it a practical fit for the tight, distributed monitoring points typical of modern data center cooling systems.

Measurement Principle

The pFlow MFR measures flow velocities from 0.03m/s to 5.0m/s with ±2.0% accuracy and 0.4% repeatability, using the ultrasonic transit-time principle combined with a clip-on transducer design. By monitoring flow rates in cooling loops, the MFR helps balance the cooling load across multiple servers and racks, while regular flow data can help predict potential issues before they cause system failures, allowing for timely preventive maintenance.

The MFR can also detect unexpected changes in flow rates, which may indicate leaks in the cooling system, helping data center operators prevent equipment damage and unplanned downtime. This combination of precise measurement and anomaly detection makes the MFR a valuable diagnostic tool as well as a routine monitoring instrument.

Engineering Design of the pFlow MFR

The pFlow MFR is sized for DN10 pipes (OD 13.5mm to 18.5mm) and compatible with stainless steel, PVC, copper, and PPR materials. Its all-in-one transmitter pairs with a clamp-on transducer via a 5mm six-core cable at a standard 2-meter length, and the unit carries an IP54 enclosure rating for reliable operation in data center mechanical spaces.

The MFR supports LoRa communication with a maximum transmit power of 22dBm, operating across -40°C to 85°C, with selectable frequency bands (EU868, US915, CN779, EU433, AU915, CN470, AS923) for global deployment flexibility and optional LoRaWAN protocol support. A 1.54-inch LCD color display with 240×240 resolution and three touch keys enable straightforward field configuration, and a standard RS485 interface with FUJI and MODBUS protocol support provides a wired alternative for facilities preferring conventional BMS integration.

Key Features

The pFlow MFR combines micro-pipe precision with long-range wireless connectivity for data center applications. Core capabilities include:

Compact DN10 clip-on design purpose-built for data center cooling loop monitoring.
LoRa and optional LoRaWAN wireless communication for distributed IoT monitoring points.
±2.0% accuracy with 0.4% repeatability across a flow velocity range of 0.03m/s to 5.0m/s.
Cooling loop optimization, chiller system monitoring, and leak detection capability.
Selectable LoRa frequency bands for regional and global deployment flexibility.
Standard RS485 interface with FUJI and MODBUS protocol support as a wired alternative.
1.54-inch LCD color display for straightforward on-site configuration and diagnostics.
IP54-rated enclosure suitable for data center mechanical room environments.

Industrial Applications

The pFlow MFR is purpose-engineered for data center cooling applications across Oman, including cooling loop optimization, chiller system monitoring, water-cooled server flow measurement, cooling tower efficiency tracking, and precision cooling for high-density server racks. Its wireless LoRa connectivity is particularly valuable in large data halls where running cable to every monitoring point would be costly and disruptive.

As the officially authorized partner for pFlow Gentos, Seven Star LLC distributes the MFR to colocation facilities, enterprise data centers, and IT infrastructure operators throughout the Sohar and Salalah economic zones and the broader GCC region, alongside applications in agriculture, healthcare, and aquaculture where its compact size and wireless connectivity add value.

Why Choose Seven Star LLC for Data Center Cooling Networks

Data halls in Oman are increasingly distributed across multiple cooling zones, and running dedicated cabling to every DN10 monitoring point in an already-built facility is often impractical, which is exactly the gap the MFR’s LoRa connectivity is meant to close. Seven Star LLC’s engineers assess gateway placement and frequency band selection before an MFR order ships, so operators get reliable wireless coverage across server rooms, chiller plants, and cooling towers rather than discovering dead zones after installation.

As the authorized regional partner for pFlow Gentos, we also help data center and colocation operators plan leak-detection thresholds using the MFR’s flow-anomaly capability, and can coordinate multi-unit orders for facilities standardizing cooling-loop monitoring across multiple data halls 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.
