VGM

Thermal mass flow meter based on high precision MEMS technology
(CMOS sensor). Pressure and temperature insensitive
according to the CTA constant temperature principle. Also insensitive
to pressure surges.

(DIN62684), optionally external power +12 ...+30 V DC (max. 200 mA)

Display: Touch-display 128 x 64 px, blacklighted only with external
power supply (Micro-USB or 24 V DC)

Electrical connector: optionally length 2.0 m, with free ends at 24 V DC
Function: totalisator included, physical units can be changed

Alarm functions: 3 configurable alarms,
programmable as = low alarm, high alarm, window alarm and totalizer alarm.
The alarms can be configured with different parameters as delay and alarm duration.
Relais: switching current up to 1A, switching voltage 30 V DC
