Output The output is a current-sinking pulse (square wave) compatible with many controls in addition to the Seametrics indicators and transmitters. The most common of these are water treatment controllers and programmable logic controllers (PLC’s). For these units, it is sometimes necessary to provide a pull-up resistor if the controller does not provide for a current-sinking output.
TX800 SERIES INSTRUCTIONS OPERATION AND MAINTENANCE Caution: Never remove the u-clip retainer when the pipe is under pressure. Always remove pressure from the pipe before attempting to remove the meter. Removal under pressure may result in damage or serious injury.
