Smart control of hydraulic parameters
Intelligent stop of pump at no flow condition
Below minimum control frequency, MIDA gradually reduces the pump speed while monitoring the pressure transducer signal. If this value is maintained close to the set pressure, MIDA will reduce the output frequency until stopping the pump definitely.
Dry running alarm via cosphi value
If the pump runs dry, its cosphi value drops below a settable cosphi value, and MIDA stops the pump after 3 seconds. MIDA will try to make 5 attempts every 10, 20, 40, 80 and 160 minutes, after which it will trigger an alarm and stop the pump if the condition persists.
Maximum and minimum alarm pressure
When the pressure rises above a certain settable pressure value, MIDA will stop the pump to prevent damage to the hydraulic components in the system. Similarly, if the pressure drops below a certain pressure an alarm is triggered and the pump is stopped.
Loss compensation proportional to the water flow
If the pressure sensor is placed near the pump, with the increase in flow the pressure value at the furthest outlet is lower than the set pressure. It is possible to vary the set pressure in proportion to the frequency to compensate pressure loss in the pipes.
