The model rcd flow meter from kobold is used to measure and monitor the flow of liquids and gases. Depending on the model, the measuring range of the device is from 3 to 2300 l/min for water and 6 to 2800 nm3/h for air. It can also be used to measure/monitor other liquids and gases. The functional principle behind this meter is the venturi tube.
In the housing there are passages that register the resulting differential pressure and transmit it to a bellows system located in the display housing. The bellows system is protected by stop pins whenever the maximum rated flow is exceeded.
With mechanical displays, the flow value measured by the bellows system is transferred to and indicated by means of a pointer element on the calibrated display [in l/min for water and n/m3/h for air].
With electronic displays, a hall sensor converts the mechanical movement into an electrical signal. The strength of this signal varies with the flowrate. Various electronic systems are available to display or monitor and evaluate the flow volume.
Specific display scales are available for use with any media at any pressure and temperature.
This flow meter is appropriate for use in the following areas of application: machinery, plants, chemical and pharmaceutical industry, heavy industry as well as the beverage and luxury-foods industries.
These devices have the following particular advantages:
No moving parts, universal mounting, self-monitoring, easy operation.
Their measuring accuracy is 3% of the upper range value, with a reproducibility of 1%, also of the upper range value. The maximum service temperature is 100°c for a needle indicator and 80°c for an electronic display.
Connections: ½" bsp to 3" bsp, ½ npt to 3 npt
