Dual Chanel Ultrasonic meter

FEATURES

– Stratified fluid piping design for two-channel measurement, measurement accuracy

– Range than the width, and less than 0.01m / s starting flow

– Display large amount of information, with the screen display 9 digital display four cumulative flow and instantaneous flow figures

– Design of energy-saving, power-saving features such as automatic meter will empty tube or long-term fluid standstill

– Full IP68 protection class design, the components completely sealed to protect, even if the water can be long-term work

– Design at the time, there were a total of records and data collection functions on the month, day

– With multiple communication interface mode; TTL level pulse output and USART interface for easy connection to other low power devices; standard RS485 interface;

infrared communication interface; support CJ-188 communication protocol.

– Supports standard MODBUS, M-BUS, HART communication protocol, compatible communications protocol Haifeng ASCa code

– Output signal and diverse: Available two isolated pulse signal output, ( which pulse and pulse width equivalent programmable) ; may also 4-20mA two-wire output

– With online software upgrades

– With Dual PT1000 temperature measurement function, can achieve heat measurement

– Built-quantitative control can be achieved manually or set the time automatically start controller, thus achieving automatic timing quantitative or

quantitative irrigation water

– Depending on customer needs to select a variety of units, including cubic US gallons, cubic feet and liters

– Built-in lithium battery, the battery life of more than 6 years
