 Principle of principle and thermal pressure table 


 Description: 
 ALICAT gas mass flow meter has been well studied using two physical properties of gases: pressure and viscous to measure the flow. By measuring differential pressure laminar flow unit to calculate the flow, this measurement is inherently linear. Using differential pressure, absolute pressure, and temperature sensor to measure and compensate for the gas pressure, temperature, measurement standard state (such as an atmospheric pressure @ 25 ℃) the volume of the gas flow. Measure 4 parameters: mass flow, volume flow, temperature and absolute pressure, the optional total flow, and can be displayed simultaneously by dynamic display. Optional battery makes this product easy to carry, commonly used in the testing and calibration tools. Also provides customized to meet your specific needs. 
 ALICAT using differential pressure sensor gas volume flow meter to measure the current state of the volume flow. Because it is not built-in absolute pressure and temperature sensors, the price will be cheaper, as opposed to an alternative to mass flow. 
 Local Display: 
 ALICAT All products are a standard feature to provide local display (no display products can be used for OEM). Mass flow controller and the volume flow controllers are in the main display provides information on different process parameters, users can select the primary display button (Main Mode Display) and the measured gas (calibration gas 30), PID regulator parameters, such as the measurement traffic is cleared. 









 Digital output (RS-232): 
 All ALICAT products have a standard RS-232 output. The signal through the 8-pin round connector or 6-pin industrial connector transmission. The RS-232 using ALICAT output or input port communication without special software. Any device with a terminal program, such as Windows ? operating system a "super terminal", can use our ALICAT products. RS-232 can display all of the local
