Positive Displacement Flowmeters Deliver Precision Results

KOBOLD’s DOC oval wheel flowmeters are positive displacement flowmeters where the passage of liquid causes two oval gears to rotate within a precision measuring chamber and with each rotation a fixed volume of liquid passes through the meter. Magnets embedded within the gears initiate a high-resolution pulse train output. The pulse output can be wired directly to process control and monitoring equipment or can be used as an input to instruments supplied with or fitted directly onto the meter.

The flowmeter is available as a blind transmitter with a pulse output capable of interfacing to most monitoring and control instrumentation or the meter can be fitted with reed switch. This technology allows precise flow measurement and dispensing of most clean liquids regardless of their conductivity, with other liquid characteristics having no or minimal effect on meter performance.

Additionally, the meter does not require flow profile conditioning or straight-line runs as required with alternative flow technologies, making the installation relatively compact and low cost. For more details, peruse the DOC Oval Wheel Flowmeter datasheet and user manual.
