Oval gear flow meter with threaded connection / Aluminium casing and PEEK sensor
型號：Type VO…AP Thread- very good accuracy and repeatability
- low pressure drop
- suitable for industrial and chemical liquids, mineral oils and fuels
- insensitive to vibration, pressure changes and viscosity changes
-
The SIKA oval wheel meters were developed for volume and volumetric flow measurement of liquids. They are used in applications such as lubricant monitoring or food and beverage production.
- displacement flow meters with direct recording of the volume
- no inlet and outlet sections required
- high-quality construction for long service life and high reliability
- high long-term stability
- high measuring accuracy and repeatability
- easy installation
Oval wheel meters are displacement flow meters that transport defined partial volumes in individual measuring chambers. The sensor element consists of two high-precision, toothed oval wheels that are driven by the flow of the medium and roll upon each other. With each revolution of the oval wheel pair, a specific volume is thus transported. The number of revolutions is the measure of the amount of liquid passed through. The revolutions are recorded by a sensor element.
