With calibration valve for calibration
WIKA Merna Tehnika d.o.o.
The WIKA gas density measuring instruments provide reliable warnings against dangerously low gas levels, even under extreme ambient conditions. Electrical switch contacts warn the plant operator when the gas density drops below defined levels due to leakage.
Via the on-site indication, the pressure based on 20 °C [68 °F] can be read directly on the instrument.
With regard to switchgear safety, asset protection and environmental protection, it is common to perform functional checks on a regular basis. Article 5 of EU regulation no. 517/2014 on fluorinated greenhouse gases, provides for checking of the leakage detection system at least every 6 years if it contains > 22 kg [48.50 lb] SF6 gas and the plant was commissioned after 01 January 2017.
With the help of the firmly welded calibration valve, the gas density monitor can be shut off from the process and calibrated without having to disassemble it. This not only reduces maintenance time but also minimises the risks of SF6 gas emissions and potential leakages during recommissioning.
When connecting a calibration system (e.g. model ACS-10 or model BCS-10) to the calibration valve, the gas density monitor is automatically disconnected from the gas compartment and a calibration can be performed. Following the calibration process, the calibration system can then be disconnected from the calibration valve and the connection to the gas compartment is reestablished automatically.
The calibration valve is also available as a retrofit solution for gas density monitors already installed in the field, as model GLTC-CV, and can be mounted between the gas compartment and gas density monitor.
