Low Cost Case Drain Monitoring

A case drain flow meter is used to measure the hydraulic fluid flowing back from the case drain of a pump or motor. This fluid is usually leakage within the pump or motor due to internal clearances. Monitoring this flow is crucial because an increase can indicate internal wear or damage, signaling potential failure. A lower-cost flow meter can effectively detect these issues early, helping to prevent major failures, reduce maintenance costs, and ensure the reliable operation of hydraulic systems.
