The V25 is a totally new kind of visual indicator that can be used to monitor flow in pipe systems or liquid level in tanks and vessels.
For flow applications the V25 visual indicator is supplied with a flow-sensing paddle suitable for use in pipes both large and small. Designated V25F, the visual flow indicator is a self-powered magnetically operated insertion indicator that can be used in pipes ranging from 25mm (1”) upward. The indicator simply screws into a standard pipe tee or socket and provides a clear bright red or green face as an indication of flow or lack of flow.
The V25F flow indicator is available with a normally red face that changes to green when flow is detected. Normally red is the standard configuration and is supplied as the default model unless otherwise specified. The indicator is also available with a normally green face that changes to red when flow is detected. The reversed colour models can be used to indicate danger when flow is present.
Visual flow indicators generally have heavy glass or plastic pressure windows that allow an operator to view the process liquid. The V25F uses a unique coloured flag to indicate flow or lack of flow. The flag operates magnetically in a sealed see through chamber. There are no pressure windows to fail in the V25F flow indicator. The V25F can be used in coloured or turbid liquids. It can also be used in air and gases and in liquids containing solids. When fitted with a suitable trailing wire sensor it can even be used in effluent and sewage applications.
