 "summary": "The Smart Strainer kit measures inlet and outlet pressure and temperature across a strainer screen and works out how full the basket is. On strainer models with an automatic flush ball valve it opens the valve when the pressure drop passes a set threshold. Over BACnet MS/TP it reports seven Analog Inputs, five alarm and status inputs and a flush status value.",
