Oval gear flow meters work with the displacement principle and are used for measuring, counting and monitoring of viscous liquid flows. The Oval wheel counter flow meter consists of one case, in which two geared oval wheel gears are. The space between the gears is filled with the medium. The medium is responsible for the rotation of the gears depending on the volume throughput.  In the gears are the permanent magnets, which deliver impulses to the electronic. A down streamed electronic evaluates the signals and depending on the strengths it starts delivering scaled impulses and/or a 4-20 mA signal.

Nutating disc meter work with the displacement principle and are used for measuring, counting and monitoring of viscous liquid flows till a viscosity over 700 mPas. The nutating disc meter consists of one case, in which a disk gets whirled by the volume flow. This disk is attached to the bottom and to the top with spherical calottes and straggles in dependence to the volume throughput in the measuring chamber. With a permanent magnet the disk delivers impulses to the electronic. A down streamed electronic evaluates the signals and depending on the strengths it starts delivering scaled impulses and/or a 4-20 mA signal.

Magnetically inductive flow meters work with the Faraday´s cage of induction. This cage of induction said, that an electrical voltage is getting induced in a magnetic conductor, which moves through a magnetic field. In case of the electromagnetic flow measurement, the moving conductor is replaced by the flowing fluid. The conductive liquid, which needs to be measured, flows through a non-magnetically pipe, which is electrically insulating from the inside. The two measurement electrodes supply the induced voltage, which is proportional to the flow velocity, to the transducer. The flow volume is calculated with the diameter of the pipe.

Ultrasonic flow meter measure the speed of the flowing medium with acoustical waves. The ultrasonic flow meters consist of two parts: the sensor (ultrasonic sensor) and the analysis unit (transmitter and transducer).
The acoustic flow measurement has the advantage towards other measurement procedures, that it is independent from other properties like electrical conductivity, density, temperature and viscosity. Also the missing moving mechanical parts reduce the maintenance costs and no pressure lost due to arrowing of the cross section will result. For the use in industrial installations there are two main measurement principles: the Doppler-ultrasound-procedure and the transit-time-ultrasound-procedure.
Transit-Time-Ultrasound-Procedure: The medium has to be preferably homogenous and should contain as less solid contents as possible. An acoustic wave is sent with a 45° tendency against the flow and another acoustic wave is sent with a 45° tendency with the flow. This happens mutual. The wave with the flow spreads faster, than the one against the flow. The transit times are measured continuously. The difference of the transit time is proportional to the mean low velocity. The flow volume per time unit is the result out of the mean low velocity multiplied with the respective pipeline geometry of the measurement transducer.
Doppler-Ultrasound-Procedure: The frequency deferral of the sent signal is captured because of the flow velocity of the inhomogeneous parts in the medium. Therefore reflection points (air bubbles, pollution particles) are necessary. In pipes which are only filled partly the fill level needs to be identified additional to the flow velocity, so that the flow can be calculated.

Turbo meters are indirect volume meters. A rotor gets into turning through the axial incident flow. The motion is getting transferred outwards either in electronically, mechanically or magnetically. Depending on the type, there are different options and applications possible, for example airplane or coffee machine.

Variable area flowmeters are robust, affordable meters with direct display for the flow measurement of oil, water and other kinds of liquid. It’s flexible and easy to install them in every position (vertical/horizontal) without losing measurement performing.
A variable area flow meter consists of a case, in which a cone is pushed up by the volume flow. Because of that there is a constant pressure lost, which is dependent on the own weight of the suspended body less the Archimedean boost.

Impeller meters are speed recorders, which determine the volume depending on the dimensions of the pipe and the speed of rotation of the impeller. The flow sensor is an impeller construction with a non-magnetic sensor mechanism.
The impeller shape and the missing magnetic resistance justify the resistant accuracy and repeatability in the sensor area. When the impeller gets rotated through the liquid, a weak signal gets transferred with a frequency proportional to the flow.

Mass meters work with the Coriolis force, which is developed through the Coriolis acceleration. The physical principle says that the force has an effect on a moving mass in a rotating system.
The pipe bend is set into vibration by actuators. The axis of rotation is the base of the pipe bend. The arms oscillate and form a pitch circle. The speed on one point on the arm is faster the bigger the distance between the point and the axis of rotation is. When the pipe is flowed through, the mass has to be faster as soon as the fluid is entering.  According to the law of inertia the liquid in the left arm is delayed = with a lag. The medium in the summit of the arch has reached its maximal speed.
The medium, which flows to the axis of rotation in the arm, reaches constantly places with low speed. The inertia force of the Coriolis Effect pushes the liquid in the arm in direction of vibration. The liquid in the arm runs at a higher speed.  When you look at the moving pipe loop from the front, you can see that both legs don’t move in a row anymore. The time difference depends on the oscillation frequency, the mass of the medium, the liquid velocity and the temperature-dependent elasticity of the pipe.
Therefore this procedure is able to measure the mass flow directly, instead of measure it via other properties like volume, density, viscosity.

Differential pressure flow meters belong to the dynamic pressure measurements. An aperture restricts the constant flow of the fluid in a pipe, so that the speed gets faster on that point. Therefore the static pressure reduces in accordance with the Bernouille theorem. The hereby emerging pressure difference is called the effective pressure and is measure for the flow (volume flow and mass stream). The pressure difference for liquids is developed by the Bernouille theorem. Pitot tubes work also with the Bernouille theorem. In contrast to the venturi tube there is a second pipe, which is specifically located, so that the flow reaches one tube opening frontally. In front of the pipe a dynamic pressure emerges, behind the pipe a static, unchanged pressure emerges. Through different forms of the tube openings, the measurement results can get influenced. Through tube openings in form of an ellipse in the dipstick, permanent low pressure lost can be reached (Typ Ellipse®). Tube openings in form of a trapeze in the dipstick hamper the flow and establish high flow resistance. All the devices can be installed vertical or horizontal.
