SP2A/HP3D to Aquamaster 3 and Aquamaster 4
The purpose of this guide is to ensure successful installation of two Taggle SP2A tags, providing both forward and reverse readings for an ABB AquaMaster 3.
Required:
2 x Taggle SP2A devices.
1 x ABB WABC2010 military plug
Step 1 - Designate Forward and Reverse Devices
It is crucial that forward and reverse pulse SP2A devices are differentiated from each other. Use electrical tape, a cable tie or otherwise, to distinguish the Reverse flow SP2A (shown in Figure 1).
Mark the cable-end with a pen/marker, write ‘REVERSE’ so there is no confusion.
Figure 1: Above are two Taggle SP2A tags. Distinguish between forward AND reverse tags by placing coloured tape at the base.
N.B. Taggle Systems’ convention is to label the Reverse flow Tag only, as shown above.
Step 2 – Preparing Device Cables
Function | Colour |
Tamper | Yellow |
Tamper Ground | Black |
Counter | Red |
Counter Ground | Blue |
Table 1: input/output connections of SP2A
In order to interface with the sensor, the cable ends must be prepared.
Strip 3 cm off the white outer sheath to expose the coloured cables from the ends of both tags, being careful not to cut the coloured core cables.
Figure 2: Strip the white outer cable to reveal the 4 core cables; black and yellow core cables have been shortened.
Shorten the black and yellow cables to 2 cm, and strip back the insulation to expose 1 cm of wire.
Twist the pair of black and yellow cable together and solder/crimp tube them to form a connection, as shown in Figure 2.
Place heat-shrink or electrical tape over the black and yellow connection.
Strip back 1 cm from the blue and red wires.
Twist the blue wires from each tag together, this will form the common ground connection.
Figure 3: Twist the blue wire from bot SP2A’s together.
Place heat-shrink over the twisted pair of blue wires and over each red wire.
Place a 5 cm long piece of heat shrink around both Tag cables (See Figure 3).
Figure 4: White heat-shrink over outer tag cables and yellow heat-shrink over the black and yellow core cables.
Step 3- Preparing the Plug Cable
In this step, the WABC2010 plug is prepared, so that it may be connected to the SP2A’s.
The WABC2010 plug contains 7 core cables, as per Table 1.
Table 2: input/output connections of WABC2010
Important: For this interface to work O/P2 must be set to Reverse Pulses, and O/P1 must be set to Forward pulses. ABB specifies this to be the factory setting on this flow meter. Refer to ABB manual to confirm.
Shorten the length of the plug cable as required to fit in the housing where the sensor and SP2A’s will be placed.
Strip 4 cm from the cable to expose, coloured input/output connections.
Leave only the Yellow, Red and Orange core cables from the plug. Trim the rest down to the base of the black sheath.
Strip 2 cm from the Yellow, Red and Orange core cables to expose the plug wires that will be connected to the SP2A’s.
Step 4 - Connecting the Devices to the WABC2010 Plug
The requirements are that the joint be strong enough to last at least 10 years and weatherproofed.
Solder both blue wires from the SP2A’s to the yellow WABC2010 wire.
IMPORTANT: Depending on which Taggle device is designated for Forward or Reverse pulses, determines which red wire from each Tag connects to either the Orange or Red plug wire.
Solder the red wire from the SP2A designated to record FORWARD pulses to the Orange WABC2010 wire.
Solder the red wire from the SP2A designated to record REVERSE pulses to the red WABC2010 wire.

Slide the heat-shrink tubing to cover the solder/scotch lock/crimp tube joint used to connect the core cables and use a heat-gun to shrink the tubing.
Figure 6: Finished connection between Tag and sensor
Step 5 - Connecting The sensor to The AquaMaster 3 meter.
As seen in Figure 6, the WABC2010 sensor connects to the port closest to the power supply port i.e., the second from the left-hand side of the AquaMaster 3.
Figure 7: The WABC2010 plugs into the flowmeter as shown above.
Step 6 - Finalising Installation/Recording information
As shown in Table 2, an example is provided of all the necessary information that must be recorded upon installation.
Important: ABB claims factory setting for the pulse rate on the Aquamaster 3 is 1000L/pulse. But previous installs indicated the pulse rate as 100L or 10L/pulse.
A supplementary meter read/time should be taken a few days later to confirm the correct pulse rate.

Device Positioning
Always mount the device as high as possible, and at least 1M above ground height.
The top half of the device houses the antenna, which must never be adjacent to metallic surfaces such as star pickets or water pipes.
Keep the devices at least 30cm from obstructions such as walls, electrical cabinets, pump housings etc.
Avoid deploying devices inside metallic enclosures such as sheds or fuse boxes as metal shields the radio signal from the device.
As far as possible avoid deploying devices under foliage such as trees and shrubs.
Any position which has a clear Line of Sight (LoS) to the receiver will be superior to Non Line of Sight (NLoS) positions.
