Oil Flow Meters UK
Here at Litre Meter, we specialise in the design, manufacture and supply of flow meters. On this page you can find a wide range of expertly crafted oil flow meters, including fuel meters, heating oil flow meters and inline oil flow meters.
For measurement ability over wide ranges and, if needed, at extreme pressures, we recommend the VFF meter. This state-of-the-art piece of equipment has been developed for 30 years to have pinpoint accuracy and extreme durability.
Listed below are all the flow meters within our range that are suitable for oils, fuels and other similar liquids:

Rotary Piston Meter
Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. Inside the chamber, a rotating/reciprocating mechanical unit is placed to create fixed-volume discrete parcels from the passing fluid. In the VFF the rotor is basically a disc shape with an annular groove on its underside capable of holding and transporting flow from the chamber inlet to the outlet i.e. a rotary piston. The units are manufactured in 316 stainless steel or titanium. They can measure pulsing flows. Suitable for a wide range of fluids from Methanol to Epoxy resin. 0.01 to 33,000 l/hr. +/-0.5% accuracy, +/-0.25% repeatability.
Pelton Wheel Meter
Also known as a radial turbine the highly efficient Pelton Wheel meter has some major advantages. The very large blade area compared with the flow inlet port size produces an exceptionally wide range flowmeter which can measure very low flows. The flow through the inlet of the meter is accurately directed onto the rotor which rotates at a speed in linear proportion to the flow rate. A small sensing coil detects the ferrites mounted in the flow meter rotor blade tips as they pass. No drag is imposed on the rotor which assists in the measurement of extremely low flows. Sapphire bearings provide a very low friction mechanically-robust bearing with long life characteristics. Turndown can be as high as 280:1. Ideally suited for low viscosity constituents measurement up to 2″ pipe sizes and larger and up to 10cSt. 0.003 to 500 l/min; ±2.0% of reading (also 1.0%); some models suitable for flow measurement at higher pressure.
Vortex Mass Meters
Vortex and other types of ‘oscillatory’ flow meters utilize the behaviour fluid oscillations in order to derive flow rate. This technology works by inducing fluctuations in the fluid properties such as pressure, density or viscosity which can be converted into a flow rate. These flowmeters are normally calibrated on water. No moving parts and relatively tolerant to particulate flow these find many applications where temperatures are high or where other more traditional flowmeter technologies are out of spec. +/- 1.5% rate, 1/2″ to 8″ and insertion.
Ultrasonic Flow Meters
Ultrasonic flowmeters measure the travelling times (transit time models) or the frequency shifts (Doppler models) of ultrasonic waves in a pre-configured acoustic field that the flow is passing through to determine the flow velocity. The Sierra range of ultrasonic (transit time) Innovasonic devices are available, click for details. Litre Meter has access to other ranges but the Innovasonic is relatively unique as not only are fixed and portable ultrasonics available but also insertion devices for tougher applications. Ultrasonic flow meters can measure water and other liquids over a range of velocities and with a certain amount of solid content. 25mm to 10000mm;±1.0% of reading (also 0.5%); 0 to ±40 ft/s (0 to ±12 m/s).
Inline ‘axial’ turbine flowmeters are velocity measuring devices – they measure the average velocity of a fluid flowing through the body of the meter. Mounted within the body of a liquid turbine flowmeter is a vaned rotor. The rotor is centred on a shaft and allowed to rotate on bearings. The shaft is supported in the housing by tube bundles that also provide a measure of flow conditioning for the fluid stream. Good for low viscosity epoxy and catalyst flow metering. Wide size range and excellent accuracy. 0.24-17 up to 3028-56775 litres/min. Overrange 150% intermittent. ±0.25% reading – typical. ±0.1% repeatability.
Helical Screw Meter
Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. Inside the chamber, a rotating/reciprocating mechanical unit is placed to create fixed-volume discrete parcels from the passing fluid.
The helical screw principle uses 2 counter rotating gears to form a continuous constant volume cavity. The SRZ is a stainless steel version suitable for high viscosity and abrasive media flow metering. 0.04 to 400 litres per minute, +/-0.1% accuracy, +/-0.05% repeatability. Housing in 316L and 303 with screws in 1.4122 (430), tungsten carbide bearings and FKM or PTFE seals. Pressures to 400 bar, -40°C to 150°C.
How do Oil Flow Meters Work?
Oil flow meters measure the amount of liquid (in this case oil, fuel or similar) that flows past the systems sensors. While there is variation in the way different machines’ sensors work, the oil flow meter working principle is the same as any other: to produce precise, repeatable measurements for a specific application.
Different types of flow meters work in different ways. For example, vortex flow meters work by detecting vortices shed off a bluff body. The perturbations are counted and are used to convert this into a flow rate. This is one of the most versatile models of flow meter and is widely used for steam and low viscosity oil, particularly at high temperatures.
Another example is turbine flow meters. These are also very versatile, but are particularly good at measuring low-viscosity liquids (ie. engine oils designed to reduce fuel consumption) with steady, medium-to-high speed flows.
