5.5.2 TM80 meter
As described in the Certificate but having internal modifications to the SM80 meter which
reduces drift over the meter lifespan. This meter is designated the TM80 meter.
The TQP pumping unit and TM80 meter are shown in Figure 33
5.6 TQM meter
Having the TQM meter fitted. This meter is similar to the TM80 meter as above but with
modifications to the piston seals (Figure 34).
The meter may be used for dispensing traditional petrol and diesel products; but may also be
used for dispensing biodiesel blends of up to 20% biodiesel, and ethanol petrol blends of up to
15% ethanol. The aluminium components may optionally be anodised resulting in a dark grey
external finish. The meter will typically dispense an 85 % ethanol blend, but may dispense up
to 100% ethanol. This is shown on the component label with the added reference, “For use
with E85.” This is subject to the bio-fuels not having excessive water content.
With this meter the models may optionally carry the alternative names Q110, Q210, Q310,
Q410, and Q510 in order to highlight alternative hydraulics being employed.
6 ALTERNATIVE ELECTRONICS
6.1 Model 6 Alternative Display head electronics
The electronic calculator known as Model 6 comprises the following modules:
Power to calculator and displays
Controls Hydraulic modules and communicates with
Interfaces nozzles pulsers and solenoids to computer
board
6.2 Opto isolator
As described in the certificate, and any compatible variants thereof, but having a Veeder Root
single channel opto isolator. The device provides an optically isolated RS232 interface and
connects any tank gauging system to any Kiosk Control Unit, or any Point of Sale Terminal
approved under this certification for connection to the KCU, or any DOMS controller which is
approved under this certification or any compatible variants with an existing RS232 output port
and having a current valid until date. The device allows communication of tank related data.
The tank gauging system provides the power source for the opto isolator.
This opto isolator is primarily intended for the connection of a tank gauging system. However
there may be any peripheral equipment connected to the opto isolator in use for management
purposes only. The peripheral equipment must provide the power source for the opto isolator.
