Introduction
The Seraphin Motor Fuel Calibration Trailer is a mobile system for calibrating gasoline and diesel fuel dispensers. It features precision volumetric stainless steel provers and holding tanks, including a Series J prover for high-speed diesel dispensers.
Set-up Procedure- Ground the trailer using the provided cable to prevent static electricity.
- Unlock and level the provers.
- Close all drain valves and inspect the prover for debris.
- Wet the prover by filling and draining it once to ensure measurement consistency.
Calibration Procedure- Fill the prover to its nominal capacity.
- Level the prover and compare the meter reading to the scale.
- Drain the prover into the holding tank, ensuring no spillage.
Gravity Draining- Connect the drain hose to the tank and route it to the storage tank inlet.
- Open the drain valve and monitor the process to prevent spills.
- Ensure all residual fuel is drained before disconnecting the hose.
Proving Run with Series J Prover- Perform the wetting procedure.
- Drain the prover using the pump-off system, ensuring safety precautions are followed.
Testing Procedure- Ground the trailer.
- Fill the prover and compare readings.
- Drain the prover safely.

Refer to NIST Handbook 44 and API Manual for official procedures.
Maintenance and Care
Provers: Regularly check for leaks and damage.
Trailers: Ensure tires are properly inflated and inspect lights, brakes, and axles.
Pumps: Follow safety guidelines and maintenance instructions to prevent overheating and damage.
Hitching and Loading- Securely hitch the trailer and connect safety chains.
- Ensure proper loading to avoid exceeding weight limits.
General Safety
Read all manuals before operation and ensure all safety measures are in place to prevent injuries and equipment damage.
Operating Instructions and Safety Precautions- Only pump liquids for which the pump is designed. Avoid flammable or corrosive liquids unless specified.
- Ensure the pump is not operated with closed suction or discharge to prevent overheating.
- Verify the correct direction of rotation to avoid damage to the pump.
- Position the pump accessibly and close to the liquid source.
- Check lubricants before installation and operation.
- Use appropriate lifting equipment for pump handling.
- Self-priming pumps must be filled with liquid before operation to avoid damage.
- Allow overheated pumps to cool before removing any components.
- Regularly check the suction strainer for clogs.
- Secure the pump to prevent movement during operation.
- Do not operate pumps in explosive environments unless designed for such use.
- Inspect the pump for shipping damage upon delivery.
- Avoid wearing loose clothing around machinery.
- Lock control panels in the OFF position before maintenance.
- Drain pumps before freezing weather.
- Do not work alone in underground pump systems without ventilation.
Terminology- Bottom Loading: Filling method using a bottom load adapter.
- Nominal Capacity: Volume designation of a test measure or prover.
- Cubical Coefficient of Thermal Expansion: Material expansion due to temperature change.
- Field Standard Test Measure: Handheld measure, typically under 40 liters.
- High Resolution Standard: Used for precise measurement control.
- Main Flow Cessation: Transition from full discharge to a trickle.
- Prover: Device for measuring liquid volume, can be filled from top or bottom.
- Reference Temperature: Temperature for nominal capacity measurement.
- Sight-flow-indicator: Visual flow observation fitting.
- Submerged Fill Pipe: Minimizes foaming during top filling.
- To Contain/Deliver: Volume adjustment indications for standards.
- Tolerance: Maximum permissible error.
- Vapor Recovery: System for collecting vapors to prevent atmospheric release.
Safety Considerations- Users must establish safety practices and comply with regulations for hazardous materials.
- Safety devices and locks should prevent unauthorized equipment operation.
- All electrical connections must be explosion-proof and comply with the National Electrical Code.
Warranty Information- Pemberton Fabricators, Inc. warrants products against defects in material or workmanship for one year of use or 18 months after shipment.
- Liability is limited to repair or replacement of defective parts, excluding expendable items.
- No liability for special, indirect, incidental, or consequential damages.
