| 20090133489 | Equipment for Measuring Gas Flow Rate - In a flow sensor, detecting elements are provided at a sub-passage. A sub-passage wall contains a hole to drain accumulated liquid. A protrusion arranged close to the hole on an external surface generates dynamic pressure on the opening in response to external flow. Alternatively, a protrusion upstream from the hole on the inner wall surface produces a separation flow area for separating the flow from the internal surface near the hole, whereby pressure in the separation area is reduced and almost the same pressure differences on the internal and external surfaces openings result. This reduces leakage from the hole and changes in the distribution flow in the sub-passage between cases where the hole is blocked and not blocked, thus minimizing flow measurement errors. Structure may be provided close to the external surface hole opening to prevent a liquid film or drop from being formed on the opening by surface tension. | 05-28-2009 |
| 20090217752 | Sensor Unit for Fluids - The static pressure, the differential pressure, and the temperature must be known in order to be able to determine the mass flow rate, the volumetric flow under standard conditions, or the enthalpy flow of a fluid.

Said sensor unit outputs a value which also takes other parameters and/or physical constants into account to a control unit that is connected downstream, whereby some of the computing is advantageously done in the sensor unit while some load is relieved from the control unit. | 09-03-2009 |

| 20100005876 | THERMAL FLOW METER - A thermal mass flow controller or mass flow meter having a novel sensor housing that reduces heat conduction from the housing mounting plate or base to the sensor itself. The housing also greatly minimizes the thermal gradient that can result from the uneven application of heat to the housing base. This reduction is accomplished in part by the use of one or more thermal isolation slots to isolate the upper portion of the housing (which holds the sensor) from the lower portion of the housing. Heat transfer to the sensor housing is also minimized by raising the middle portion of the bottom of the housing so that thermal contact is made between the base and the housing only at the two ends of the housing. | 01-14-2010 |
