Hydrosmart
M521 / M531
M5 Family Multifunction Intelligent Controller M5 for One Pump
The intelligent pump controllers - HydroSmart M521 and M531 - are a practical, simple, compact and highly automated solution for the management of differential pressure systems, sewage systems, rainwater, wastewater ejectors and lifting, transfer or pumping of water for a pump, replacing the traditional boards that are manufactured by basic protections in metal boxes.
Typical applications for hydrosmart M521 / M531
Differential pressure equipment
Use with pressure switches, dry pump protection by float, electrodes or without electrodes
Drainage Equipment / Ejector
Use with floats or electrodes, Built-in buzzer type overflow and fault alarm
Lifting Equipment
Use with floats or electrodes, dry pump protection by float, electrode or without them
