Case drain

Lake’s Case Drain Monitor is an affordable option to using a standard flow meter for case drain applications. It offers a flow measuring accuracy of ±5% of range that can help confirm pump performance, identify required maintenance and reduce costly MRO down-time associated with unpredictable pump failure.
Designed for convenient vertical, horizontal and inverted installation, the monitor has a sealed window tube that makes it ideal for outdoor/exposed applications and where wash-downs may be required. And Lake backs its Case Drain Monitor with a One-Year Warranty
