Prover Calibration

Essential to maintaining measurement accuracy, provers must provide a reliable means to verify meter readings and establish and certify the meter factors. Prover calibration service can help you control product loss and gain substantial savings by providing:

​

• On-site calibration of small volume provers sizes 8” to 40”

• Water draw certificate of calibrated volumes
• Prover seal leak check, repair and upgrade services

• Inspection of hardware and electrical components 

• Quick replacement of genuine hardware parts

• Upgrade recommendations to improve operation and performance of the prover 

​

Purpose of prover calibration

​

Custody transfer contractual requirements
Check mechanical conditions of the prover

Verify prover accuracy Fulfill API minimum recommended calibration every 3 years 

​

Water Draw Calibration 

​

The water draw method is one of the preferred calibration techniques. It involves displacing or “drawing off” the volume of water between the prover detectors into field test measures which are calibrated traceable to the National Institute of Standards and Technology (NIST).

Clear, deaerated water is selected as the test medium because of its stable characteristics, availability, and the relatively low effects its viscosity and surface tension has on drain time through the field test measure.

Calibration capabilities 

 

In today’s competitive environment, calibration is critical to business success. Daniel prover calibration service will keep your flow instrument calibrations up-to-date and in compliance with measurement systems regulations by using:
