About Ameren

• Ameren is a power and gas utility located in Illinois / Missouri

• They own and operate 6 fossil fuel power plants in Illinois with a generating capicity of 16,000 Megawatts

• Ameren markets and trades several thousand megawatts of competitively priced Illinois / Missouri based electric generation.

• Ameren residential, commercial, and industrial operations serve 2.4 million electric, and 900,000 gas customers in a 64,000 square mile area

• They own and operate a gas storage facility in Sciota Illinois

• Ameren was in the beginning phases of infrastructure upgrading at the Sciota gas storage facility

• Ameren came to us with a problem. • They wanted to update their existing gas well instruments at 40+ storage wells.• They were using Senior Daniels Orifice Plate meters. They have to change orifice

plates at least 3 times a year because the seasonal flow rates. • They also needed to monitor the water leaving the separator. They were using

turbine meters and Ameren knew they were inaccurate and required frequent maintenance.

• Dual channel combination Gas / Liquid meter

• One channel meters the Gas out of the separator. This channel receives Pressure and Temperature for standard volume compensation

• The second channel measures liquid out of the separator

• All of the information, flows, pressures, and temperatures can be communicated via modbus over radio modems

Customer Benefits

• Economics of utilizing 1 meter for both the gas and liquid out of the separator

• UFM’s are inherently Bi-direction which is necessary for the application

• Orifice maintenance is no longer necessary

• UFM has extremely high turndown

• Seasonal replacement of Orifice is no longer necessary

• UFM is capable of detecting low velocities that the Orifice can not see

• Clamp-on UFM is a maintanence free solution
