1.4 Major Technical Performance

1. Nominal drift diameter:（4～200）mm, refer to Table 1 for the basic parameters;

2. Medium temperature:（-20～80）°C; Split type (－20～120) °C;

3. Ambient temperature:（-20～70）°C;

4. Precision: ±0.5%, ±1％;

5. Detector signal transmission wiring system: three-wire voltage impulse (three-core

shield wire);

6. Power supply:

1) TB3WE Three Wire

External Power:12~24VDC/30mA(-20%~+15%),if no output can be as low as 6V

Battery:Lithium battery 3.6V(2/13Ah)/0.4mA

2)TB2WE Two Wire

12~24VDC/4-20mA(-20%~+15%)

7. Transmission distance: the distance between the sensor and the display instrument

may be as far as 1000m;

8. Local display power supply: 3.6V (Lithium battery, may be used continuously for

more than 3 years);

9. Display mode: local LCD displays instant flow and cumulative flow;

10. Output Signal

a)TB3WE Three Wire

1)Pulse Output:High level voltage amplitude≥5V, low level<0.5V

2)Three sire 4-20mA linearity correction current output(need ground wire)(load

resistance≤800Ωat 24V)

3)RS485 communication:flowmeter with RS485 interface, communication distance

1200mm.

b)TB2WE Two Wire

1) Two wire 4~20mA linearity correction current output(need ground wire)(load

resistance≤600Ωat 24V)
