Series BAT Blind Analog Transmitter

Converts Pulse Frequency to 4 to 20 mA, Loop Powered

The Series BAT Blind Analog Transmitter is a non-indicating, 4 to 20 mA transmitter for use with the Series EFS2, IEFS, PDWS, TBS and FLMG. The BAT is easy to set up and can be either wall or meter mounted. It takes a pulse frequency output from the compatible flow meters and converts it into a continuous 4 to 20 mA analog output signal. The frequency for the flowmeter output signal can be adjusted using four rotary switches on the back of the transmitter and a microcontroller automatically scales all other values accordingly. The microcontroller is also able to average inputs for more stable reading outputs. The rate for averaging is adjustable and ranges from 2 to 16 seconds. Power for the BAT is supplied by a current loop, making only 2 wires necessary. This unit features high environmental protection with semi-flexible urethane potted electrical components.
