A digital oil flow meter is a flow instrument used to measure the flow rate of oil in a system and display the readings electronically. Unlike mechanical oil flow meters, digital oil flow meters use electronic sensors and processors to provide more accurate and reliable oil flow measurements., meanwhile provide analog 4-20mA, pulse output, HART ,MODBUS or Profibus DP options for integration into broader monitoring and  control systems, they are widely used in various industries where precise monitoring of oil flow is essential.
