The visual inspection of the passage of liquids, gases and other substances in the factory process is a vital element and can be quickly and effectively achieved with Val.co’s visual flow indicator, which can be installed regardless of whether the factory is automated or not.
Jan Grobler, Managing Director of GHM Messtechnik South Africa commented: “There are four system-centric visual flow indicators: rotor, sphere, turbine and piston. All four aspects provide engineers with a quick solution. Used for flow evaluation in the factory process. The visual flow indicator provides a well-lit and easy-to-check function. Val.co is part of the European-based GHM Group, and all its flow indicator products have the expectations of European-made meters high quality.”
The rotor is an element that displays flow, with several rotating blades positioned perpendicular to the flow direction. It is supported by a rotating shaft with ball bearings to reduce friction and increase rotation stability. Grobler said: “The liquid or gas to be monitored enters the observation tube and can be controlled in terms of mass and flow. The rotation speed is proportional to the speed of the controlled fluid.”
The liquid or gas to be monitored enters the transparent dome. The position of the sphere inside the transparent dome controls the velocity and flow rate of the fluid.
The element that shows the flow rate is a turbine with a propeller oriented in the direction of flow. The turbine is supported by a rotating shaft with ball bearings to reduce friction and increase rotational stability. The liquid or gas enters the observation tube inside the turbine housing.
The piston sliding along the shaft is contained in a transparent glass observation tube, and the liquid or gas to be monitored enters the observation tube. The position reached by the piston in the tube is proportional to the velocity of the controlled fluid.
Grobler explained: “All four visual flow indicators provide a rotational speed that is proportional to the speed of the fluid under control.” “They are cost-effective and simple devices, and are very easy to install, so that engineers can be clear and precise Visually confirm the state of the fluid being checked. They can be performed on closed or open systems.”
The visual flow indicator ranges from DN8 to DN50, the maximum temperature is 200°C, and the maximum flow rate is 190 l/min.
