Propane Handling Components 1

Meter:
• High accuracy to 0.25% from 1 to 60 litres (16
gallons) per minute with standard meter.
• Magnetic coupling for pulser drive eliminates shaft
seals, a major cause of product leakage common with
competitive meters.
• High quality and precision components: use of
stainless steel components with roller bearing running
surfaces provides consistent accuracy and reliability.
• All meters are factory calibrated before installation in
dispensers. They are then calibrated again as
14
completed dispensers.
Propane Handling Components 2

Pressure Differential Valve:
• Built-in excess flow valve, cannot be accidentally or
improperly adjusted and ensures protection in case of
hose failure.
• Internal shut-off valve to prevent flow below 15 psi
pump differential pressure.
• Integral dispenser "blow down" service control valve
for the depressurization of the entire dispenser.
• Integral hydrostatic relief valve protects components.

Propane Handling Components 3

Piping System:
• All internal lines are high pressure seamless steel
tubing (maximum working pressure 6000 psi).
• All fittings are listed by Underwriters' Laboratories and
CSA for working pressure exceeding the maximum
tubing pressure.
• All fittings incorporate reusable ferrules (the portion of
the fitting which seals the fitting and the tubing)
allowing the fitting to be reused after servicing.

Propane Handling Components 4

Dual Solenoid Valves:
• Every transaction starts in slow flow mode while the
dispenser computer verifies that the temperature
sensor and pulser system function properly. If correct
operation is detected, the fast flow valve opens,
allowing the transaction to continue.
• An error in the temperature or pulser system will shut
down the transaction. A pulser not sending any
pulses will prevent the fast flow solenoid valve from
opening, thus alerting the operator to the problem.
• At the end of the transaction slow flow mode is used
17
to accurately stop at pre-set amount.
