Sometimes due to leakage in the hydraulic system or due to negligence of the machine operator, the hydraulic oil level goes down and the hydraulic pump gets ceased immediately. The Cost of this hydraulic pump & hydraulic oil are very high. We have developed an electronic system, which indicates (Display) the hydraulic oil level pre-set in tank, to the machine operator. These systems also give an alarm at low oil level to alert the operator to take the necessary action. The intelligent electronic system is also capable of shutting down the total system just before the oil level goes empty.
