The air current passing through the instrument is in proportion to the speed of the rotor. To measure speed, the instrument is provided with a tube (12) which is axially located centrally to the rotor rotation plane. In the tube is inserted a speed meter probe (13) coupled to a ...
PURPOSE:To make accurate pressure correction without changing the position of a pressure detector, etc., and to measure an air flow rate precisely by performing the pressure correction arithmetic of an air flow rate detection signal according to a specific arithmetic expression by using a signal fro...
The Laval Questionnaire is a valid measure of health-related quality of life in patients with morbid obesity and is responsive to treatment-induced changes.Background Obesity is defined by a body mass index (BMI) greater than 30 kg/m2; when the BMI is greater than 40 kg/m2, obesity is mo...
FlowTrax is a real-time ultrasonic airflow monitor designed for mine ventilation optimization. FlowTrax provides highly accurate measurements for velocity, direction and volume of air movement. It is designed to measure flow in underground tunnels as well as primary and booster fan flow output....
The turbine flowmeter is considered one of the main traditional flowmeter technologies, as differential pressure types and positive displacement meters. They still are a favorite device used to measure gas flow, particularly for a clean, medium-to-high steady flow of low-viscosity fluids. The turbin...
PURPOSE:To accurately measure a flow velocity without being affected by the change in temperature by making the resistance value of a flow velocity measuring thermistor equivalent to a heating temperature obtained by an arithmetic unit and rendering the difference between a fluid temperature and the he...
(IR FPA) measuring system is a portable type instrument, which is re-designed to measure the thermal phenomena in high temperature up to 700 掳C or ... J Morikawa,M Zamengo,Y Kato - Thermosense: Thermal Infrared Applications XXXVIII 被引量: 1发表: 2016年 Changes in the Glow Curve of...
PURPOSE:To accurately measure the flow rate of fluid in a flow passage by an easy method by throwing and dipping a transmitter in the fluid in a closed or open passage where unfilling fluid flows. CONSTITUTION:The measuring instrument consists of the transmitter 1 to be dipped in the fluid ...
Instrument to measure the frequency of sound I need an instrument to measure the frequency of the sound of a vibrating violin string for a high school research essay. I tried using a Labquest and a vernier microphone to measure but it was way too imprecise. I need the instrument to very ...
smart electronic circuitry, the products offer unprecedented cost-effectiveness with performance. The sensors directly measure mass flow with a very low pressure loss, opt with various wireless transmissions, and control ON/OFF valve. The current models can be readily applied to many process ...
