Gas meter test and calibration device (Bell Prover)

Bell Prover is a system used for calibration of gas measuring equipment with different capacities at a constant pressure. Displaying capacity, pressure and flow rate, Bell prover is an appropriate device for calibration of domestic and commercial gas meters. All the testing gas meters’ data, temperature, pressure and displacement information are sent to the related software for calculation, measurement and recording. All the test steps of the system are done accurately by its special software. The software’s user-friendly and graphical environment, easily guides the operator step by step to fulfill the test completely.

This system is accurately designed and manufactured according to highest standards, by EGC R&D team, calculating and correcting manufacturing, volume, temperature and pressure uncertainties.

Optional features:

• Capability to install pressure drop calculation (∆P)systems for each gas meter
• Capability to set up a web based system to record the meter readings and collecting statistics from the device.
• Capability to offer the device without smart system
• Capability to configure the device so that can calibrate different sizes of gas meters

Specifications:

• Ability to test and calibrate all types of diaphragm, ultrasonic and other gas meters in different sizes and capacities
• Full- automatic calibration system
• Windows ® operating system , user-friendly, full graphical and easy to use software
• Smart system (Automatic calibration of the system before each testing step)
• Determining the error percentage of gas meters and determining the type of modification gear by software
• Exclusive Balance System for rapid and unrestricted calibration of the system
• The initial isobaric error correction system
• utilizing oil Anti-turbulence system (oil orifice)
• Determining the oil type (oil with special viscosity)
• Considering full ergonomics tips for operators in design of the table(Increasing labor productivity and reducing operator mistakes)
• Meter reading via sensors (reducing calibration time operator mistakes)

High quality design and manufacture, calculating and correcting manufacturing, volume, temperature and pressure uncertainties.
