About Flowline Systems
We offer a full range of metering technologies from the worlds leading flow meter manufacturers. Because we are independent we can offer the best technical solution for your flow application, this means a working solution the first time, every time. We specify and supply flowmeters for all meter applications including water, steam, gas, and dust. Many of our flowmeters are “retrofittable” which means installation without shutdown.
Our customer base is very extensive. We supply all the UK water companies, power generators including CHP as well as nuclear and hydro generation. We supply aerospace, defense, chemical, petroleum, and environmental sectors. Our meters are also widely used in the food, brewing, and manufacturing industries.
The Product of Flowline Systems
Steam Flow Meter

DF25 Steam Flow Meter – Insertion Pitot
The DF25 is a Steam Flow meter suitable for pipes DN100-2500mm. The right Steam Flowmeter can save you money on your steam generation costs thus helping to reduce any Steam wastage. The DF25 Steam flow meter is designed for the minimum pressure drop saving you money. The DF25 Steam Pitot is designed to be an extremely accurate way to measure your steam flow.
Steam Flow Gauge, Mechanical, Large Dial, Flo-Gage
Inline Mechanical Steam flow gauge with a direct reading dial. The Flo-Gage is a direct reading DP flow meter that displays your flow rate in a “speedometer” style display. As your flow increases the needle moves around the face of the display. These do not require any power to function and have large easy-to-read dials.
Steam Flow, Multivariable transmitter, 4-20mA and Hart, IMV30T
The IMV30T is a Multivariable Transmitter with HART enable 4-20mA. This Multivariable Transmitter measures your differential pressure and absolute pressure. The IMV30T can also take a PT100 input to give you a full corrected steam flow output via the 4-20mA.
Sewer Flow Meter

Sewer Flow Meter, non-contact, Raven-Eye
The Raven-Eye is an advanced, non-contact RADAR flow meter for open-channel flow measurements. It uses non-contact radar technology to measure the flow from above the channel. Suitable for open channel flow measurements such as sewer flow measurements, river flow measurements, flow to sewage treatment works, discharge consent metering, and final effluent flows.
The Raven-Eye is combined with IFQ Monitor to give you a local display, 4-20mA outputs, logging capability, and error signaling. Alternatively, it can be connected to the Web-enabled UNI-Trans for advanced multi-sensor applications
IFQ Monitor for the Raven-Eye Phoenix and Beluga
The IFQ Monitor is an easy-to-use and configure, converter and display (and optional logger) unit for the Raven Eye flow sensors. The IFQ Monitor connects to the Raven Eye flow sensor via RS485 and to an external level sensor (normally the ULS-02) via a 4-20mA. The IFQ Monitor has three 4-20mA outputs Flow, Level and Velocity all of which can easily configure via the keypad.
Open Channel Flow Meter, Doppler, Wetted, Beluga
The BELUGA combines most advanced ultrasonic Doppler velocity sensing with most modern and powerful digital DSP processor technology resulting in more representative velocity data. This advanced architecture of the BELUGATM provides users desiring in-depth analysis with:
- Real-time spectral analysis of the velocity distribution through the cross-sectional area
- Measurement validation through quality parameters
- Auto-diagnostic tools
Combine the BELUGA with an IFQ MONITOR for stationary flow monitoring or with an IFQ LOGGER for portable/temporary flow monitoring.
Ultrasonic Flow Meter

Fixed Clamp-on Flow Meter with Datalogger, Minisonic
The new Minsonic is an AC-powered, fixed Clamp-on flow meter with an internal datalogger, The Minisonic is suitable for pipes from 6mmOD all the way up to 10 meters. it is suitable for media that are water-based. Easy installation with no flow shut down required. Simple setup via front keypad. The Minisonic has a 4-20mA output, 2off isolated contact outputs, Mobus TCP through Ethernet, internal data logger downloaded via USB.
Portable Clamp-on Flow Meter with Datalogger, MinisonicIIP
The MinisonicII Portable is a handheld, battery-powered, clamp-on flowmeter with an internal flow logger. It has a high-contrast LED display, a long-life battery. With a range of sensors that are suitable for pipes from 10mmOD to 10 meters. It is an ideal test piece if you have pipes you need to know the flow quickly and easily.
Electromagnetic Flow Meter

Electromagnetic Flow Meter Mag 5100w
Electromagnetic Water Flow Meter MAG 5100W is an electromagnetic flow sensor designed to meet various water metering requirements such as chiller flows, test rigs, cooling flows, groundwater, drinking water, wastewater, sewage, and sludge applications.
Electromagnetic Flow Meter MAG1100
Chemical Electromagnetic Flowmeter, MAG 1100 is a chemical electromagnetic flow sensor in a compact wafer design. It is designed for flow applications in the process industry.
Electromagnetic Flow Meter MAG1100F
The MAG1100F is Food-grade Hygenic Flowmeter designed for the food and beverage industry. Suitable for conductive Liquid flows including Water, Beer, Wort, Dairy, Milk, Cream and many others. The Mag1100F is also widely used in the Pharmaceutical industry as it can be steam sterilization at up to 150°C
Coriolis Mass Flow Meter

Coriolis Flow Meter Mass Flow FCS330
The sensor is protected in a pressure-rated stainless steel enclosure. In non-Ex applications, two purge ports support the installation of a pressure guard. The modular transmitter is designed for compact and remote installation, easy to mount on a wall or pipe. Available from 15-150mm in diameter.
Coriolis Flow Meter, MassFlo MC2 DN50 to 150 Mass Flow Sensor
The MC2 Mass Flow Meter is suitable for accurate mass flow measurement for all kind of liquids due to the high accuracy, which is better than 0.15% of the mass flow rate. Due to the versatility the meter, it is easy to install and is recognized for its high accuracy in a wide turndown range which is paramount in many applications.
Coriolis Flow Meter, MassFlo 2100 DI3-40mm Mass Flow Sensor
The MASS 2100 DI 3-40 is suitable for accurate Mass Flow Measurement for all liquids and gases. The full bore design provides lower pressure loss due to same internal diameter throughout the entire sensor, and the single tube construction without internal welds, reductions or flow splitters offers optimal hygiene, safety and CIP cleanability. The sensor is also characterized by having a large dynamic turn down range better than 500:1 and the market’s biggest wall thickness, ensuring optimal lifetime and corrosion resistance as well as high-pressure durability.
