SETTINGS, CALIBRATION and FREQUENCY GENERAL INFORMATION, SPECIFICATIONS and INSTALLATION GENERAL INFORMATION INSTALLATION The Dwyer Instruments Inc. Series BAT is a blind (nonindicating) 4 to 20 mA transmitter, designed for use with Series EFS2, IEFS, PDWS, TBS and FLMG flow sensors. It accepts a pulse frequency input from the flow sensor, and converts this input into a continuous analog output signal. Power for the transmitter is taken from the current loop itself, so only two wires are required.
