AFT-1E
The AFT-1E transmitter has been designed for the measurement of air
flow. It gives a voltage or current output proportional to air flow.
The AFT-1E transmitter makes possible precise local adjustment
and remote measurements, optimization and energy monitoring system.
As an air flow monitor, the AFT-1E can monitor leaks or blocked
up ducts, the condition of filters, the freezing of coolers or heat
exchangers, state of adjustment, condition of fans etc. |
