GAS FLOW METERS |
|
The BI-1000 series of Gas Mass Flow Meters ranges from 2 sccm (standard cubic centimeters per minute) to 1500 SLPM (standard liters per Minute). Full scale accuracy of +/- 1% is standard. Units to 400 SLPM can be re-ranged in the field or by the factory. Units from 400 SLPM-1500 SLPM can also be re-ranged in the field or by the factory. Each group has a re-ranging kit offered specific to its flow range group (See Re-ranging). BI-1000 series Gas Mass Flow Meters utilize differential and absolute pressure sensors and a temperature sensor in an LFE (laminar flow element) system, and correct for changes of pressure and temperature to standard flow conditions of 1 Atmosphere and 25 degrees C. Corrosive gases are a strength of the BI series. The BI-2000 series of Gas Volumetric Flow Meters ranges from 2 ccm (cubic centimeters per minute) to 1500 LPM (Liters Per Minute). Full scale accuracy of +/- 1% is standard. Units to 400 LPM can be re-ranged in the field or by the factory. Units from 400 LPM-1500 LPM can also be re-ranged in the field or by the factory. Each group has a re-ranging kit offered specific to its flow range group (See Re-ranging). Volumetric Flow Meters are often used where gas flows to 'vent' and volume of gas metered does not change because of changes of back pressure and flow stream temperature. |
