Model CRU

WHAT IS IT? The Model CRU is an advanced version of our standard rotating paddle style level control designed to provide a positive indication that the unit is functioning properly. The failsafe detection is based on our proven motion control technology.

WHY IS IT NECESSARY? The Model CRU is appropriate for critical applications where spillage or overfill is detrimental to the process or the environment, or to the safety of personnel. The Model CRU not only monitors the process, it monitors itself.
