Description

Overview

The pFlow P118i Portable Ultrasonic Flowmeter represents a pinnacle in non-invasive, temporary flow measurement technology. Designed for field engineers, maintenance teams, and water management professionals, this completely portable device allows for rapid flow audits without the need to cut pipes or halt industrial processes. As the official authorized partner and exclusive regional representative for pFlow Gentos, Seven Star LLC is proud to supply this advanced metering solution to critical infrastructure projects, water treatment plants, and industrial complexes across the Sultanate of Oman, Muscat, and the wider GCC region.

Housed in a rugged, handheld form factor and equipped with a brilliant 3.5-inch TFT color display, the P118i empowers technicians to conduct highly accurate spot-checks, verify the performance of existing inline meters, and perform comprehensive leak detection surveys. Its non-contact architecture ensures that the device never touches the internal fluid, making it the absolute gold standard for hygienic applications such as municipal drinking water supply networks and pharmaceutical processing.

Measurement Principle

The foundational operational mechanism of the P118i relies on highly accurate transit-time ultrasonic flow measurement. The unit utilizes a pair of external clamp-on transducers that transmit and receive high-frequency acoustic signals diagonally across the pipe wall and into the fluid medium. By calculating the exact time difference (transit-time) between the upstream and downstream signal propagation, the internal microprocessor determines the precise fluid velocity.

This advanced acoustic processing algorithm dynamically filters out ambient pipeline noise and adapts to varying fluid profiles. Because the sensors are completely isolated from the internal fluid, the measurement principle introduces zero pressure drop, prevents mechanical wear and tear, and completely eliminates the risk of cross-contamination in pure-water or corrosive fluid applications.

Engineering Design

The physical architecture and electronic engineering of the pFlow P118i Portable Ultrasonic Flowmeter are meticulously optimized for rapid deployment and maximum field mobility. The primary transmitter unit features an integrated, high-capacity rechargeable Lithium-ion battery, providing up to 10 hours of continuous operation in remote locations where AC power is unavailable. The 3.5-inch high-resolution backlit screen offers exceptional readability even under direct sunlight, paired with an intuitive keypad for seamless on-site parameter configuration.

The device is universally adaptable to a massive range of standard pipe sizes, specifically engineered to accommodate diameters from as small as 15 mm up to a massive 6000 mm. Furthermore, the acoustic transducers are factory-calibrated to penetrate various standard pipe materials, including carbon steel, stainless steel, copper, PVC, and HDPE. For comprehensive data analysis, the unit features an integrated SD/TF card logger, allowing engineers to record thousands of data points for later download and compliance reporting.

Industrial Applications

The extreme portability and non-intrusive design of this ultrasonic flowmeter make it an indispensable asset across continuous-process industries and municipal water infrastructure. In the large-scale desalination plants and water distribution networks of Oman, these meters provide field engineers with the precise volumetric data required to conduct raw water audits, calibrate older mechanical meters, and detect hidden pipeline leaks.

Food-and-beverage processing facilities and pharmaceutical manufacturers across the GCC rely heavily on this technology for life-science grade liquid measurement. Because the sensors never touch the internal water, strict sanitary conditions are effortlessly maintained. As the officially authorized partner for pFlow Gentos, Seven Star LLC distributes these portable meters to major industrial contractors, HVAC maintenance firms, and utility providers within the Sohar and Salalah economic zones, empowering them with data-driven water stewardship capabilities.

Transducer Hardware and Enclosure Ratings

Field survivability is what separates a portable audit instrument from a panel meter, and the pFlow P118i Portable Ultrasonic Flowmeter is specified accordingly. The standard CP magnet portable transducers attach to ferrous pipework magnetically, so a single technician can position, space, and re-seat them without straps or a second pair of hands, and they are supplied with a 5 m cable that gives useful reach around insulated headers and pipe racks. The transducers themselves are of encapsulated construction rated IP68 and operate on surface temperatures from –40°C to +80°C in the standard version, while the handheld transmitter carries a NEMA 13 (IP54) rating and weighs approximately 1 kg, with an operating range of –10°C to +50°C. The stated accuracy of ±0.5% of measured value applies over the working velocity band of roughly 1.5 to 40 ft/s, with repeatability of 0.15%, which is the figure that matters when the instrument is being used to cross-check an installed meter rather than to establish an absolute total.

Data Logging and Output Options for Field Audits

For survey work the P118i logs to an 8 GB card, holding up to 512 separate files with a user-selectable logging interval from 1 to 60 seconds, so a night-flow leak survey or a 24-hour chilled-water balance can be captured at fine resolution and exported for reporting without any manual transcription. Alongside the analogue 0/4–20 mA output into a maximum load of 750 Ω, the instrument provides an OCT pulse output adjustable from 0 to 9999 Hz and a relay output switching at up to 1 Hz, which allows a temporary meter to drive a totaliser, a data logger, or a simple alarm contact for the duration of a trial. Seven Star LLC supplies the P118i configured with the transducer set matched to the pipe sizes on site, since correct transducer selection and spacing remain the single largest influence on field accuracy.

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.
