VA 570 is an air flow sensor with an integrated measuring section.

Measuring head(sensor) and body allows easy detachment for calibration and maintenance.

Flange or thread versions are available.

Removable measuring head allows easy cleaning, calibration, etc. without removing body
Calorimetric measurement does not require compensation for temperature and pressure
Integrated Modbus Output; allows monitoring of status effectively
robust design available for use in explosive area

These air flow sensor are ideal for compressed gases.

Range of 1/2" to 12" pipe

Accuracy:  ± 1.5 % of m.v. ± 0.3 % of f.s.

                  on request ± 1.0 % of m.v. ± 0.3 % of f.s.

Notes: m.v. =  of meas. value 

            f.s.  =  of full scale

Gives accurate flow rate and totalizer on display.
Accomodate adjustments for reference conditions.
Communication with Modbus RTU.
Simple installation under pressure.

VA 520 is the economic model for compressed gas flow meter.
