Gas: On-site calibration optimised at the metering skid

On- เพรสเชอร์เกจ of measuring instruments is often very time-consuming and expensive. This is also true for applications with several measurands. One of these of this may be the metering skid, something for the custody transfer measurement of the amount of natural gas transferred. A global player in the industry from Saudi Arabia has now significantly streamlined the testing process at this point: with the multi-functional CPH8000-P1 calibrator from WIKA, a ?calibration laboratory in a case?.
The center of a metering skid is the flow computer. It processes the info from all the measuring instruments and calculates the exact amount of gas that flows to the client. Natural gas is compressible, therefore the tabs on pressure and temperature during gas transfer plays a crucial role.
Verification is the law
Because even small measuring errors could cause noticeable losses in turnover, the measuring instruments should be calibrated regularly. This is usually done at the facility. Each on-site calibration must be verified relative to regulations. This implies proving consistent repeatability of the test outcomes and traceability to the assigned references. In addition, the regulations require the test equipment to be approved for use in hazardous areas.
In view of the requirements, the calibration personnel of WIKA customers previously had to utilize many different pieces of equipment so that you can adequately fulfil their tasks. In addition to pressure and temperature calibrators, this included a pneumatic pump for the test pressure, a HART� communicator and a resistance decoder. The on-site calibration cost effort and time accordingly.
The CPH8000-P1 multi-functional calibrator significantly reduces your time and effort necessary for on-site calibration.
Four measuring channels
The gas company in Saudi Arabia has reduced this effort in a single fell swoop with the CPH8000-P1 portable multi-function calibrator from WIKA. The case-mounted instrument calibrates pressure measuring instruments together with resistance thermometers and thermocouples. The test pressure is generated having an integrated pump. The CPH8000-P1 has four measuring channels. It could thus perform and display around four measurements simultaneously. The ATEX-approved version also supplies the test items and reference sensors in the metering skid with voltage (DC 24 V) without danger.
Documentation without problems
During the test procedure, the CPH8000-P1 ? via its integrated HART� module ? communicates directly with the measuring instruments, which may also be HART�-capable. Its powerful data logger and the very large memory capacity support the user in the next documentation of the on-site calibration. The unit provides all the information relevant for verification.
Note
Detailed ไดอะแฟรม on the model CPH8000 multi-function calibrators is available on the WIKA website. Each instrument has a modular design and will therefore be specified for the respective selection of applications. Should you have any further questions, your contact will gladly assist you to.
