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.

2150EX Flow Meter for Zone 0 locations
Area Velocity meter - Baseefa approved as ATEX Group II, Category 1G
The 2150EX is an intrinsically safe Area Velocity Flow Meter that is specifically designed and Baseefa-approved for use in Zone 0 and Zone 1 potentially explosive atmospheres under ATEX Directive 94/9/EC.
The AV 2150EX smart Area Velocity probe is built on digital electronics, so the analog level is digitized in the sensor itself. The probe is also factory-calibrated for 3 meter span at different temperatures. This superior built-in calibration eliminates temperature drift in the level signal, providing long-term level stability that reduces recalibration frequency and completely eliminates span recalibration.
The 2150EX is powered by two lithium or rechargeable lead acid battery packs, or by the 2194EX network interface module. Highly efficient power management provides battery life up to 8 months with two-minute data storage interval.

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.

the VSE series VS and VHM the Ecoflow sensor
measures viscous media, however as in-linedevice.

The programmable flow display evaluates the pulses
from the magnetoresistive pickup and shows the
chosen units on a backlit LCD-display. Alarm and
condition reports are signalled in the display by a
red LED with additional text. The measured values
are transmitted by means of an analogue output, 0
or 4 … 20 mA, and 0 or 2 … 10 Volt by means of
a resistor (500 Ohm). The limit values are signalled
through two transistor switching outputs.

The rotation of the flowmeter gear wheels is sensed
by a non-contact magnetoresistive pickup, amplified
and emitted as pulses. The passing of each
individual gear tooth produces a pulse corresponding
to a precise positively displaced measured
volume. The pulse output can be produced as PNP
or NPN signals. The frequency is proportional to
the momentary flow.

Oval type flow meters are a complete flow measurement and monitoring system for re-circulating oil systems.
The method of measurement is based on the rotation of special oval designed gears – the speed of which changes in proportion to the flow of oil through the meter. This gives a visual indication of the flow rate through the transparent cover and also sends electrical pulse signals to an electronic monitor or PLC to provide actual flow figures.
This also provides information to allow either low or high flow monitoring to be provided.
Measurement is independent of viscosity and therefore a real flow will be indicated throughout the temperature range.
Pressure drop through the flow meter is relatively low.
The flow meter is designed to pass a small flow even if the gears are prevented from turning due to solid particles contained in the oil. This prevents complete starvation of oil to bearings etc.
