FTLU Vortex Flowmeter Wiring

 

 

Here to introduce FTLU Vortex Flow meter wiring

Wiring for output frequency signal of Vortex Flowmeter

This meter uses three wires to transmit frequency output signal to other external equipments, with power supply 24V ±10%, the minimum load resistor of output circuit 10kΩ, the maximum capacitance 0.22µF, and resistance of shielded wire must be less than 50Ω.

Normally, a three cores shielded wire (RVVP3×0.5mm2) is used as connecting wire. The shielding layer should be connected to the grounding screw in amplifier box reliably.

Appropriate shielded wire should be used to meet field temperature when meter used in high or low temperature ambient.

When the atmosphere surrounded the field contains oil, solvent or other corrosive gas and liquid, appropriate shielded wire should be used to meet this environment.

Connecting wire should not be parallel to the power cable, with distance between them more than 15cm at least. Place them in independent steel tube would be better. Fix connecting wire and can not be shaken.

 

 

Wiring for RS-485 Communication Vortex Flow meter

Four wires transmission is applied between vortex flow meter with RS-485 output and other equipments. Power supply is 24V DC ±10%.

Normally, 600V PVC insulated wire or cable should be used as connecting wire. The two cores shielded wire (RVVP2×0.5mm2) should be used where electrical noise occurs likely. The shielding layer should be connected to the grounding screw in amplifier box reliably. Appropriate shielded wire should be used to meet field temperature when meter used in high or low temperature ambient.

When the atmosphere surrounded the field contains oil, solvent or other corrosive gas and liquid, appropriate shielded wire should meet this environment.

 

 

Wiring for Vortex flow meter with two-wire 4~20mA output signal

This meter uses two-wire to transmit 420mA output signal to other equipments, with power supply 24V DC

±10%, the maximum load resistance for output circuit 600Ω(including resistance of cable).

Normally, 600V PVC insulated wire or cable should be used as connecting wire. The two cores shielded wire (RVVP2×0.5mm2) should be used where electrical noise occurs likely. The shielding layer should be connected to the grounding screw in amplifier box reliably.

Appropriate shielded wire should be used to meet field temperature when meter used in high or low temperature ambient.
