The middle field heap are medium weights (probably actual baseballs), whereas those in the seats are positively lightweights (perhaps Wiffleballs?). In effect we have invented a weighing machine that determines mass from the item's trajectory in a crossing discipline. Can we use gravity as the crossing discipline for atoms and molecules? The petrochemical, gas processing, biogas, landfill and gas pipeline industries has at all times needed an correct and dependable, low upkeep and cost efficient CO2 analyzer for high quality and course of control purposes. KECO has met these requirements with the proven microprocessor primarily based analyzer. The CarbonHound supplies steady on-line analysis based mostly on the specific non-dispersive infrared principle of operation. 1.5 SCFH. Next, the pattern is introduced to the specific infrared detection element that provides an output proportional to the focus of carbon dioxide. This sign is digitized and analyzed by the advanced microprocessor HMI (Human Machine Interface) and related software leading to a 4-20 mA output, relay alarms, and RS-485, TCP/IP Ethernet.

VERSATILE INTERFACING — through TCP/IP, RS-232, USB, analog & digital I/O, and/or non-obligatory Bluetooth. Home SERVICE AND Assist Center — our US-based mostly gas analyzer service, maintenance, restore, and calibration center is predicated in Cincinnati, OH. This central location makes product support handy and helps with fast turnaround time and environment friendly shipping. The ULT series is a simplified design for less demanding functions. The UGA system makes use of a two-stage pressure reducing inlet to sample gases at atmospheric stress. After the stress is reduced to around 10-6 Torr, the gas stream is sent to a mass spectrometer (residual gasoline analyzer—RGA) which measures the focus of every mass of interest. This instrument is a self-contained analyzer for measuring hint amounts of a chosen gas using diode laser optical absorption with wavelength modulation spectroscopy (wms) detection. The analyzer is absolutely automated upon energy-up. A LabView-based program is provided to learn, display, and log fuel concentration, temperature and strain measurements, and instrument diagnostic codes on the consumer's laptop. Readout is through a USB port configured for serial transmission and is obtainable for consumer-customized information acquisition programs. The fundamental unit requires person-provided sampling lines.
