Compound Meters

Core composition: Composed of a combination of turbine components and disk components, the components of different models of composite watches are matched differently (such as 3 "TRU/FLO consisting of 3" TT turbine components and ⅝ "T-10 disk components).

Performance reference: It is necessary to separately refer to the performance specifications of the corresponding turbine components and disc components. The 4 "/6"/8 "/10" HP TECTUS III turbine components have dedicated performance parameter tables.

Installation process

Pre-installation preparation

Tools and Materials

Essential tools: Medium sized flathead screwdriver, wire stripping pliers, hammer, ⅛ "diameter punch (or similar tools).

Essential material: # 22 AWG multi-core solid copper wire.

Optional material: Dow Corning ® # 4 moisture-proof compounds (or equivalent products).

Inspection and Storage

After unboxing, check whether the transmitter components (including the transmitter body, terminal cover, and installation ring) are intact, without damage or missing.

Before installation, the components need to be stored in a clean and dry environment, with a temperature maintained between -40 ° C and 85 ° C.

Safety and wiring specifications

Avoid placing instrument circuits near electrical noise sources such as contactors, motor starters, radio transmitters, and high-voltage power lines.

Separate the wiring of instrument circuits from other circuits and prioritize the use of independent metal conduits or metal cable trays; Long distance cabling (up to 1000 feet) requires # 22 AWG shielded twisted pair cables, with the shielding layer only grounded at the receiving device end.

When wiring needs to intersect, maintain a right angle intersection to reduce noise coupling; Use dedicated power sources (such as independent circuit breakers, isolation transformers) to ensure grounding in accordance with local electrical regulations.

Specific installation steps

1. Wiring operation

Unscrew the terminal cover screws, remove the terminal cover, thread the multi-core cable through the hole on the terminal cover, and move the terminal cover down along the cable to a convenient operating position.

Peel off the outer sheath of the cable by about 1.5 inches, separate the core wires and strip off the insulation layer of each core wire by about 0.5 inches. Use a screwdriver with a round handle to bend the bare copper wire into a hook shape.

Loosen the terminal screw of the transmitter, and wrap the hooks of each core wire clockwise around the corresponding terminal screw according to the wiring diagram (ensuring that the insulation layer is not pressed under the screw), and tighten the screw firmly (avoiding over tightening).

2. Wiring code (divided by pins)

Pin number TRICON ®/ E digital pulse type (before January 1996) TRICON ®/ E2/E3 digital pulse type (after January 1996) TRICON ®/ E/E2/E3 4-20mA type

1 connectionless high-resolution output 4-20mA source (+)

2 unconnected counting direction (ground contact closed, powered by pull-up resistor) 4-20mA return (-)

3 12-24VDC power input (+) 12-24VDC power input 24VDC power input (+)

4 Public Grounding (-) Public Grounding (-) Public Grounding (-)

5 pulse output pulse output pulse output

Note: The typical value of the pull-up resistor is 2K Ω for every 5VDC; "+" indicates that the regular current flows out of the transmitter.

3. Line testing

Connect the transmitter power and verify the output signal according to the following standards:

When there is no flow: there is no pulse at the digital output terminal, and the 4-20mA circuit current is 4mA.

At half flow rate: the pulse frequency of the digital output terminal is 1/2 of the maximum pulse frequency, and the 4-20mA circuit current is 12mA.

At maximum flow rate: The pulse frequency of the digital output terminal is equal to the maximum pulse frequency, and the 4-20mA circuit current is 20mA.

4. Final assembly

Turn off all power and apply sufficient Dow Corning on exposed wires and terminals ® # 4 compounds, the interior of the terminal cover is also filled with this compound (for moisture resistance).
