FCI: Thermal Mass Flow Meter

Sept. 8, 2014
The ST100 provides precise gas measurement for mud logging operations.

The unit can measure flare gas flows under variable and low flow rate conditions. Mud returned from a borehole contains gas that must be flared, typically in the range of 15 to 20 fps. EPA regulations require measurement and reporting of these flare gas emissions from mud logging operations. This meter provides the needed accuracy at low flow rates combined with a turndown far in excess of 100:1, with an insertion style probe offering low pressure drop. Available outputs include 4-20 mA analog, frequency/pulse, alarm relays or digital bus communications such as HART, Fieldbus, Profibus or Modbus. The meter stores up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown. Also standard is an on-board data logger with an easily accessible and a removable 2-GB micro-SD memory card capable of storing 21 million readings. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.25 to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale.
