Positive displacement flow sensor Type VZ5AL


Product description

Possible areas of application Positive displacement flow sensor Type VZ5AL

SIKA gearwheel flow meters are ideal for measuring flow rates at high or varying viscosities as used in the following application areas:

  • Consumption measurement
  • Control of filling operations
  • Dosage of oils and chemicals
  • Flow measurement of paints / varnishes



A very precisely adjusted gear pair within the casing forms the measuring element. The inflowing medium causes the gear pair to rotate. The rotary motion is scanned by contactless sensors. Since each individual tooth generates a pulse, this results in a very high resolution. Consequently, even the smallest volumes can be measured or dosed precisely.

The maximum pressure drop should not exceed 16 bar. 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.
