Affordable – Quality– Precision
SIKA VZ...Al can be used for
•Flow rate measurements
•Consumption measurements
•Dosing applications
The SIKA gear wheel flow sensors are high-precision measuring sensors for measuring volumetric flow. As they work using positive displacement, they are designed for measuring viscous, lubricating fluids such as oils. The flow sensor is not suitable for measuring water. By using certain materials such as anodised aluminium, we have succeeded in developing an excellently priced series of devices which use the tried-and-tested gear wheel process, and which are ideal for all standard applications.
Functional description
The flowing medium causes the precision gear wheels to rotate proportional to the flow rate. A non-contact pick-up measures the wheel rotation. As every tooth produces a pulse, the sensors resolution is extremely high and even minimum volumes can be measured. The frequency produced is proportional to the rate of flow. The VZ 0,2 AL-S has a 2 channel output signal with a 90° phaseshift. For standard applications the readout of one channel issufficient. In case the flowdirection should be determined, both channels must be read.

SIKA positive displacement flow sensors are highly accurate transmitters that measure volume flows. They work on the positive displacement principle.
The flowing medium causes a pair of gear wheels to rotate. The sensor is manufactured to the highest accuracy and is then precisely assembled. The rotation is scanned by two non-contact pick-offs. As each tooth generates a pulse, the resolution is very high. Very low flow rates can be accurately measured and small volumes can be dosed.
The measurement unit contains two pick-offs that are circumferentially offset by ¼ of a tooth pitch to generate a 2 channel flow-proportional frequency signal. Suitable processing of the signal provides an greater resolution and the option to identify the flow direction.
It is possible to measure not only high viscosity media but also media whose viscosity varies e.g. because of changes in temperature. The maximum pressure drop should not exceed 16 bars. This limits the measurement range of high viscosity media (see pressure drop diagrams). Basically, the measurement accuracy increases with increase in viscosity of the media.

RITTER drum-type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.
The major advantage and the superiority of volumetric Gas Meters (like Drum-type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot-wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on the measurement accuracy.

KRAL Volumeter® for research and production test stands. Laboratory measurement precision is achieved despite fast flow changes and fluid oscillations.
The ideal conditions at the Bureaus of Standards however show the potential of KRAL precision. The screw spindle-metering from the KRAL Volumeter is on one hand very robust and handles the oscillation from pressure waves. On the other hand, the spindles are very quick and can follow fast changes of the flow velocity. Optional pressure pulse compensation is available that detects transient fluid waves.

Helical flow meters are positive displacement meters with a very favourable pressure drop behaviour. They are therefore perfectly suited for the flow measurement of very high viscosity fluids.
Thanks to wide measuring ranges, high accuracy and resolution helical flow meters are an excellent choice for laminating systems, painting systems, adhesive dispense systems, PUR systems as well as batching systems for various fluids.

Screw-type flow meters belong to the group of positive displacement flow meters. Two measuring spindles with a screw-shaped profile engage with each other. They are low-friction mounted using roller contact bearings and enclosed by a housing. The liquid flow causes the spindles to rotate and passes through the device in an axial direction. In so doing, self-contained part volumes are formed which are continuously filled and emptied. This principle of measurement causes no pressure and/or flow pulsations. A sensing wheel attached to the measuring spindle is scanned by two non-contact sensors. Using two sensors, a bidirectional flow with detection of flow-direction is possible. The inflow and outflow occurs almost without deflection. Consequently, the device exhibits a relatively low drop in pressure. Measuring this way does not require the flow to be calmed at the inlet and outlet. All moving parts are lubricated by the measurement medium.

The am series volumetric flow-meter with oval gearwheels allow to perform precise and highly repeatable measurements, even with very vis-cous liquids, with up to 1,000,000 cps. The ease of use and compactness of these products, together with the possibility of installing and independent battery power supply, make them suitable to be fixed on fixed installations as well as transfer and distribution lines for fluids, both for mobile applications such as accessories for distribution valves and guns and for any other industrial application for the control of the delivered fluid.
CONNECTIONS: from 1/8” to 3”up to 1.000.000 cps
PRECISION: +/- 0,5%
REPEATABILITY: 0,03%
CONSTRUCTION MATERIALS:AISI316 - ALU - PPS
Two oval gearwheels are located inside the measuring body and, when pushed by the flow, they rotate in opposite directions; every gear contains two magnets which, coupled with an external sensor (reed type or hall effect sensor), transmit a pulsing signal. One of the sensors can be replaced by an analogue signal directly integrated in the electronic card. The frequency of the impulses determines the instantaneous flow rate, as every cycle corresponds to a given flow volume.

Chemical injection fluids are normally viscous and are therefore natural applications for the VFF meter. The flowrates are relatively low and the pressure is high compared to most general industrial applications. The VFF Rotary meter is the ideal measuring element for these service requirements. Long term stability of metering and reliability is assured by the basic simplicity of design and quality of production.
VFF Meter Design & Advantages
The heart of the VFF meter is a simple but precisely made, oscillating rotor that sits freely within the rotor chamber of the meter. It is manufactured in a variety of materials. The meter principle is of 'positive displacement'. The rotor is driven 'positively' by the flow, which passes through the flowmeter in 'discrete pockets' with minimum fluid 'slippage'. This gives inherently greater accuracy than is available from axial flow turbine type meters for a low flow of a fluid more viscous than water. Each meter provides a exceptionally wide flowrange and has excellent low flow metering capability.

These meters are mainly used for viscous fluids for flow rates of less than 8 l/min. We specialise in low flow metering noting that the meters will return a rangeability of 1000:1 for most viscous fluids applications. Materials are 316 stainless steel with a variety of rotor materials. We can measure from 0.00016 to 1750 l/min. (and up to 4000bar)
The VFF range of meters are specificaly designed for very low flow (0.0003l/min), high pressure (2000bar) hazardous area (Ateax approved) applications. They have been in service for over 15 years in the UK North sea oil and gas industry for chemical injection applications.

The Titan oval gear flowmeters work by using the liquid pressure to drive a pair of interlocking oval gears. This rotation can be detected by a variety of means to give either a TTL or contact closure pulse output. The unit is manufactured in a choice of materials and pressure ratings to suit most applications and as with all positive displacement flowmeters, the performance improves with increasing viscosity, and can achieve an accuracy of ± 0.1% of reading.
The standard range of sizes covers from 0.25” to 2” BSPF connections, with maximum flows from 1l/min to 500 L/min depending on the model. Viscosities up to 10,000cP can be measured accurately, both in forward and reverse flow. Units are available for high pressure and temperature operation.
