Repeatability

0.2%.

Measurement principle

Principle of ultrasonic propagation time difference, dual CPUs working in parallel, 4-byte floating point operation

Measurement period

500mS (2 times per second)

Working power supply

Isolated DC8-36V or AC85-264V

Signal input

3 channels of 4-20mA analog input, which can input pressure, liquid level, temperature and other signals; 2 channels of three-wire
platinum resistors

Signal output

1 isolated RS485 output; 1 isolated 4 20mA or 0 20mA output (active or passive optional)

Optional HART protocol; dual isolated OCT outputs

1 bidirectional serial interface, universal interface for peripherals, connects 4-20mA, frequency signals, thermal printers, data
loggers, etc.

Protocol

Modbus RTU protocol

Power consumption

Working current 50mA (when the keyboard is not connected and the buzzer does not sound)

2X 10  character backlight display English 

Operate

16-button or 4-button window operation

Other functions

Automatically memorizes the previous 512 days, the previous 128 months, and the previous 10 years. The positive and negative net
accumulated flow rates can be automatically remembered for the previous 30 times. The power-on and power-off times and flow rates
can be automatically or manually added, and can be read out through the Modbus protocol.

Sensor

External application, insertion and tube type

Material

Aluminum alloy or ABS
