Subject: start flow guard Z. Start flow guardSafety equipment for refiner housing pressure The flow can be set with the hand valve (A) to correct value on the flow guard, approx 1 litre/minute. The alarm limit for the flow guards is 0.5 litre/minute and a flow under that limit interlocks the production on the refiner. This because there is not enough reliability in the control of the housing pressure when the flow is too low. |
Я бы это обозвал датчиком расхода (может быть с регулируемым пределом срабатывания). |
Спасибо. |
