Modular flowmeter with area-velocity measuring probe model 2150

It belongs to the Isco 2100 system, which allows the assembly of up to 4 flow measurement units in the same unit.
The 2105 module allows connection of multiparameter probes.
The 2105G module enables communication via GSM modem.
The 2150 module performs flow measurement by area-velocity system, with head measurement with pressure transducer and velocity measurement by Doppler effect.
