Principle

Transit-time measurement principle

Display

LCD with backlight. 2x20 letters.

Keypad

4x4-key membrane keypad with tactile feedback

Input

Five channel 4-20mA current inputs for signals such as temperature, pressure, liquid level, and etc.. Accuracy 0.1%.

Two of the five input channels are wired to terminal blocks. The remaining three channels are optional.

Outputs

Analogue output: 4-20mA or 0-20mA current output. Impedance 01kΩ.

Isolated OCT output: for frequency output (0-9,999Hz), alarm driver, or totaliser pulse output, ON/OFF control, etc.

Relay output 1A@125VAC or 2A@30VDC. For ON/OFF control, alarm driver, totaliser output, etc.

Internal Alarm (Buzzer): user programmable.

External Alarm Driver: alarm signal can be transmitted to Relay or OCT output terminals to drive an external alarm.  

RS-232 serial port.

Others

Capable of offline compensation for flow totaliser, automatic / manual selectable. Self-diagnosis.

Automatically record the following information:

The totaliser data of the last 64 days / 64 months / 5 years;

The power-on time and corresponding flow rate of the last 64 power on and off events. Allow manual or automatic flow loss compensation

The instrument working status of the last 64 days
