Quantum 2 is a fully-featured pump controller, using Pulsar’s non-contacting ultrasonic technology including DATEM digital echo discrimination to provide solid performance and sophisticated level management. The unit includes 10 relays (digital outputs) and 7 digital inputs and has optional RS485 communications allowing for Modbus, and optional Profibus DP V0 and V1; enabling the status of the unit to be monitored and the controller to be programmed remotely.
Digital inputs allow the unit to respond to ‘no flow’ conditions and the Quantum 2 is able to automatically reset pumps in case of failure, saving unproductive maintenance trips to the site and freeing up staff time for more important work. The Tariff Guard routines, which are common to all intelligent controllers, ensure that energy costs are minimized through periods of maximum electricity tariff, while the Quantum’s unique ‘time to spill alarm’ protects critical pumping stations from uncontrolled overflow. The Tariff Guard All intelligent pump controllers by Pulsar Measurement operate in a highly intelligent and predictive manner: with the objective to have a ‘full’ or ‘empty’ well as the tariff changes.
The liquid level and the inflow rate is continually measured and assessed in the well. Both these variables are then related to the time the next tariff change occurs. If the next tariff charge is for a higher cost rate, the well will be filled first to enable pump down immediately prior to moving onto the higher tariff charge. This then provides maximum storage capacity in the well during the higher tariff period, once in the lower tariff cost period the level is pumped down as normal using the minimum number of pumps.
The level and inflow condition of the well is continuously monitored to optimize the liquid level and intelligently control the purpose of the pumps according to the impending tariff change. By doing this, high tariff charge pumping may be reduced significantly, or avoided entirely, to provide real cost savings on pump energy charges, especially during higher energy cost periods.
