The time to discharge the tank with varying flow rate or intermittent discharge is achieved with the Universal Tank Timer which can be also used to count the real time usage of electrical pumps used to feed the inlet of tanks meaning the life span of the feed pump is monitored in cycles. Rather than seconds or years of use. Finally this improves the system reliability, an aspect of business operations that is critical to cost and downtime in several industries. This will help monitor levels in the tank to prevent emptying without a clear level available or float control, leading to lack of useable fluids discharging from the tank when needed. The Universal Tank Timer has a complete turbine impeller inside it, which has its speed measured by the casing which holds a transducer, a hall effect sensor, that is measuring a spinning reluctor on the outside edge of the turbine providing a induced current in the transducer for every rotation. The Universal Tank Timer may be mains powered or battery operated, it can also be equipped with a transmitter to communicate with wireless technology.
