The external power supply is not greater than 35V, and the maximum current of the collector when conducting is 50mA.
	Alarm Output	Two open-collector alarm outputs with photoelectric isolation transistors. The external power supply is not greater than 35V, and the maximum current of the collector when it is turned on is 250mA. Alarm status: fluid empty pipe, excitation disconnection, flow overrun.
	Pulse output	Forward and reverse flow output, the upper limit of the output pulse can reach 5000CP / S. The pulse equivalent is 0.0001 ~ 1.0m³ / P. The pulse width is automatically set to 20ms or a square wave. Open collector output of a transistor with photoelectric isolation.
