All boiler fuel oil types require a filter. Monitoring the oil filter contamination level and cleaning or replacing it when the contamination affects the burner operation can help reduce future burner problems. The Oil Filter Monitoring Kit triggers an alarm when the oil filter needs cleaning or replacing. It does that by measuring the vacuum created by the oil pump. The higher the vacuum the dirtier the filter. Oil Filter Monitoring For Internet Communication [HT# 950093-00] 4-20mA Transmitter Interface, Vacuum Transducer.
