Name: pFlow D106E PoE Ultrasonic Flow Indicator | Seven Star LLC
Brand: pFlow

Description

Overview

The pFlow D106E is a Power-over-Ethernet ultrasonic flow indicator built for facility teams who need reliable, network-connected flow data without running separate power cabling to every transducer. Operating on the transit-time ultrasonic principle across a broad 0.5–5.0 m/s velocity range and pipe sizes from DN25 to DN600, the pFlow D106E draws both power and data over a single Ethernet run, communicating over HTTP and MQTT protocols so it slots directly into existing IT and building-automation networks rather than requiring a dedicated instrumentation bus.

As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC proudly supplies the pFlow D106E across the Sultanate of Oman and the wider GCC, complete with calibration documentation and local engineering support. Our instrumentation division in Muscat supports large-scale deployments throughout Oman’s commercial and industrial base, including data centre campuses, hospital complexes, and the Sohar and Salalah economic zones.

Measurement Principle of the pFlow D106E

The pFlow D106E measures flow using transit-time ultrasonic technology. A pair of ultrasonic transducers mounted on the pipe alternately transmit acoustic pulses upstream and downstream through the flowing liquid. The pulse travelling with the flow arrives marginally faster than the pulse travelling against it, and this time differential is directly proportional to the liquid’s mean velocity along the acoustic path.

The transmitter’s onboard processor converts this time differential, together with the programmed pipe diameter and wall data, into volumetric flow rate and cumulative totals, then exposes the readings over HTTP and MQTT for direct ingestion by monitoring dashboards or building management platforms. Because the transducers couple externally to the pipe rather than penetrating it, the pFlow D106E introduces no pressure drop, no moving parts to wear or fail, and no risk of leakage or product contamination — a meaningful advantage across the wide range of pipe materials and sizes the instrument supports.

Engineering Design of the pFlow D106E

The pFlow D106E pairs a wall-mounted transmitter enclosure with a 20×2 backlit alphanumeric LCD and a 16-key touch keypad for on-site configuration and diagnostics. The transmitter carries an IP65 rating while the transducer assembly is rated IP68, allowing installation in exposed plant rooms, outdoor pipe runs, and below-grade vaults without additional protective enclosures. Power and data both arrive over a standard PoE network cable at a 5-metre standard length, and the transducer cable itself runs a further 5 metres to reach the pipe-mounted sensor pair.

This single-cable PoE architecture removes the need for a separate low-voltage power run to each meter location, which materially simplifies retrofit projects in data centres and multi-riser mechanical rooms where pulling new power cable is the single largest cost driver. Transmitter and transducer together weigh approximately 1.1 kg combined, keeping the installation lightweight enough for standard wall anchors or DIN-rail mounting inside an equipment cabinet.

Key Features

The following capabilities define the pFlow D106E and explain its adoption across data centre and building management retrofit projects in the region:

Power-over-Ethernet design supplies both power and network connectivity through a single cable, eliminating separate low-voltage power runs to each meter location.
Dual HTTP and MQTT protocol support allows direct integration with cloud dashboards, on-premise SCADA, or lightweight IoT broker architectures without protocol gateways.
Broad flow range of 0.5 to 5.0 m/s across pipe sizes from DN25 to DN600 covers everything from small branch lines to large main distribution headers with one platform.
Compatibility with carbon steel, stainless steel, copper, and PVC pipe materials supports mixed-material retrofit projects without instrument changeover.
IP65-rated transmitter and IP68-rated transducer allow deployment in exposed mechanical rooms, outdoor runs, and below-grade vaults without supplementary enclosures.
20×2 backlit alphanumeric LCD with a 16-key touch keypad provides clear on-site diagnostics and configuration without a laptop or commissioning tool.
Purpose-built for data centre liquid cooling loops, including immersion cooling, direct-to-chip cooling, and cold-plate cooling circuits, alongside conventional HVAC applications.
Standard 5-metre PoE and transducer cabling accommodates typical wall-to-pipe mounting distances without custom cable runs.

Industrial Applications

The pFlow D106E is deployed extensively in data centre HVAC and liquid cooling infrastructure, where its PoE architecture aligns naturally with structured network cabling already present in server halls and mechanical rooms. Facility teams use it across immersion cooling, direct-to-chip cooling, and cold-plate cooling loops to monitor coolant and water-glycol mixture flow, as well as for waste heat recovery metering. Beyond data centres, the instrument serves recirculating aquaculture systems, swimming pool and commercial aquatics engineering, desalination and reverse-osmosis plants, and general water and wastewater management across Oman’s commercial and municipal infrastructure.

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.
