P4-050
Retrofit an existing mechanical LPG dispensing cabinet with a fully NTEP-certified electronic register — Handbook 44 compliant, compatible with PD and mass flow meters.
Modernize Your Existing LPG Cabinet
The P4-050 is a drop-in electronic register retrofit for existing mechanical LPG dispensing cabinets. Rather than replacing a functioning dispenser enclosure and piping, the P4-050 replaces only the mechanical register with a fully electronic, NTEP-certified measuring system.
Certified as a Retail Motor Fuel Dispenser (RMFD) under NTEP and compliant with NIST Handbook 44, the P4-050 brings legal-for-trade electronic dispensing to installations that previously operated with mechanical registers — without the cost of a full dispenser replacement.
Standard Features
Every P4-050 ships with the full Parafour electronic register feature set.
Electronic Display
NCWM retail-approved electronic display for volume and dollar totals — legal-for-trade in all commercial LPG dispensing applications.
Electronic Calibration
Field calibration via the electronic menu — no mechanical seals required. All calibration events logged in the NTEP RMFD event log.
Automatic Temperature Compensation
Standard ATC adjusts delivered volume to the 60°F reference standard per API 2450 / ASTM D 1250 for legally traceable transactions.
Multi-Level Pricing
Dual product pricing or up to 5-level pricing for fleet rate tiers, customer classes, or shift-based pricing strategies.
Electronic Totalizer
Cumulative volume and transaction totalizer maintained in non-volatile memory — accessible at any time from the menu system.
Card Reader Pre-Wired
Factory pre-wired for most commercial card reader and fuel management systems — no field wiring modifications needed.
Solenoid Flow Control
Electronic solenoid valve controls product flow for metering accuracy and provides a positive anti-siphon shutoff.
Push-To-Start / Stop
Illuminated push-button start/stop with ON indicator for clear, intuitive dispenser operation.
