Hydro-Quebec releases CRIQ report on propane tanks and meters
By Renée Francoeur
September 18, 2015 – Hydro-Quebec is releasing the conclusions of the study on the distance to be maintained between a next-generation meter and a stationary propane tank.
The study was performed by Hydro-Quebec’s research institute (IREQ) under the observation of the Centre de recherche industrielle du Québec (CRIQ). The results show that a distance of 1m between the meter and a stationary propane tank poses no risk with a simple preventive measure.
The report mentions that scenarios in which there is a leak, be it during tank filling or during regular use, “show no seepage of propane into the socket or the meter. The only scenarios in which propane seeped into the socket or the meter are those in which the regulator malfunctions or fails.” Doing the tests with the preventive measures in place showed that the flammability level was never reached under these conditions.
Further to these reports, Hydro-Quebec says it has submitted a request to the Régie du bâtiment du Québec to have next-generation meters treated the same as traditional meters, which can be located one meter from propane tanks according to standards in effect. Until the Régie make its decision, the remote service interruption function on next-generation meters will remain inactive for all non-compliant installations.
The researchers recommend orienting the pressure regulator in the direction opposite the meter. Another possibility is to install a pipe to direct the regulator outlet towards the ground. The CRIQ report states that “this solution requires very little time to implement. Pressure regulators on the market are compatible with diversion pipes.”
