Resol V40 flow meters look like normal impeller flow meters. It detects flowrate of water or water-glycol mixture and sends impulse signal to a resol controller or a resol external energy meter per 1L, 10L or 25L. 7 types of V40 flow meter are designed for different flow rates.
Grundfos VFS, RPS, VFD and RPD sensors are all two-in-one sensors working with different liquid media such as water and Glycol. Grundfos VFS and VFD measure temperature and flowrate, and Grundfos RPS and RPD measure temperature and pressure.
Resol DeltaSol MX can directly work with Grundfos Sensor VFS, RPS, VFD, and RPD.
Resol DeltaSol BX PLUS can directly woth with Grundfos Sensor VFD and RPD
Resol DeltaSol BX can directly work with VFS and RPS.
