 | | When the manufacturer first tested Sierra's Model 780S they compared it to their existing thermal meter and reported a reading error of approximately 10%. |
| | An investigation of the test conditions revealed that the competitive unit had been calibrated with air, and was scaled and linearized with a correlation based on a natural gas density of 90% methane. |
| | They have also found that the Model 780S field-configuration capability allows them to apply a correction factor to the device for a change in the natural gas mixture. |
