Energy companies focused on natural gas production, gathering, transmission, or distribution are ultimately valued on their ability to produce or deliver natural gas to its customers. Pressure and temperature measurement provides data that is required to quantify natural gas flow rates while natural gas sampling provides the heat content, or energy value, associated with this natural gas. Accurate measurement and data collection is the foundation for natural gas purchase, sales contracts and royalty payments. The underlying data that support these contracts are the ultimate economic value drivers for these energy companies
