Meister Stroemungstechnik has launched new flow monitors which were especially designed to monitor the flow of dirty fluids. These units with type declaration RMU work according to the float measuring principle. In contrast to other model series a hexagonal float instead of a cylindrical float is used. This geometry has a lower sensitivity to particles compared to the cylindrical float, which creates a small and constant circular orifice with the housing of the flowmeter.
The sturdy brass version is pressure resistant up to 150 bar and offers a high functional reliability due to its construction. The units are specified for temperatures from -20°C to 100°C. A high temperature version permits temperatures up to 160°C. The integrated return spring enables the flow monitors to operate in every mounting position. Meister offers five units of this model series with different switch ranges from 0,4 up to 18,5 l/min and the ingress protection IP 67. Customized ranges can be supplied on request. The monitoring of the limit values is carried out by means of a reed contact with an accuracy of ±10% related to full-scale deflection. If the flow rate decreases below the adjusted limit values, the contact opens. The switch points can be adjusted by the user within the measuring range.
The threaded connections are available in 1/2 inch female resp. 3/8 inch female/male at input and output.
