Aluminum gear flow-meter
SIKA
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.
