	HYDRANT TESTER

	MODEL 725:

		APPLICATION □ Hydrant tester for checking the actual amount of water available at the end of the pipe FEATURES □ Hydrant tester comprises: Hydrant meter WP-F3MB68 DN 80  Pressure gauge Carrying/protective handle Օ Input/output with fixed B-coupling □ FLYPPER electronic counter module Protection class IP68 Օ Mechanical switch for changing the display M-Bus interface to EN 1434-3 Օ No automatic display change □ Puise output: 100 l/pulse forward, 100 l/pulse return PULSE OUTPUTS The outputs are open-collector circuits. The collecter branch contains only 0 ohm rsistance, i.e. there is no internai current limiting. If required, this must be provided externally by a collecter rsistance of 1 kohm (at 30 V). The puise outputs must be operated in floating mode if the M-Bus is connected. □ Open collector (high current sink) □ Max. input voltage: 30 V □ Max. input current: 27 mA □ Voltage drop at the active output: max. 2 V/27 mA □ Current through inactive output: max. 5uA/30V □ Max. reverse polarity voltage without destruction of outputs: 6 V □ Max. current 100 mA □ Puise duration: 125 ms □ Puise break: min. 125 ms
