Type VH501 Flow switch for direct mounting Metal version for electrical and railroad applications DN 65...DN100 (DN 25...DN 50 on request) / Switching range ON 100...166,66 l/min
Conforms to the following technical regulations of railroad application: DIN EN 60077-1:2003, DIN EN 50125-1:2014, DIN EN 50216-5:2007, DIN EN 45545-2:2016 / For oil flow monitoring / For pipelines DN 65...DN100 (DN 25...DN 50 on request) / High switching currents, microswitch as signal transmitter / Optional: cable gland selectable on three sides, flanged or threaded version.
The SIKA flow monitors are ideally suited for monitoring the liquid flow of low-viscosity media in pipelines. The SIKA paddle flow monitor VH501 is especially suitable for oil flow monitoring of traction transformers in the electrical industry or in railroad and rail transport.
The flowing medium hits the impact vane, which is attached to the end of a paddle. The resulting dynamic pressure deflects the paddle and actuates a microswitch.
