The Nikkiso P-Monitor is an intelligent Power-Control unit which is based on the latest advances in Micro-processor technology. The unit measures the true power consumption of a 3 phase AC motor and shows it as a percentage of the selected power range. The power consumption (kW) is calculated from the following formula:

P(kW) = v3 x U x I x cosF (I [current] and cosF are controlled by the Nikkiso P-Monitor

The Nikkiso P-Monitor integrates a max. / and / or min. kW limit detector and the support functions necessary to establish the efficient and compact supervision or regulation of pumps.

Fuctional Description and Application

If a pump runs dry, the power consumption decreases
If the quantity of liquid pumped is higher than the design capacity allowed a max. permissible power consumption can be defined
Both values can be controlled with the Nikkiso P-Monitor and can be used to switch alarms or trip the pump. Operation against closed valve on the discharge side or the min. flow of the pump can also be controlled
