NY-M030 Series Digital Mass Flow Controller ±1％of full scale corrosive, clean, dry gas

Description

NY-M030 series digital display large flow gas mass flow
controller i s composed of mass flow sensor , thermal element ,
mass flow controller regulating valve and amplifier circuit . It uses
the flow of fluid to transfer heat to change the heat conduction
distribution effect of measuring capillary temperature distribution .
The principle i s to use the principle of temperature difference
calorimetry before and after capillary heat transfer to measure the
mass flow of the gas , amplify the flow signal measured by the
sensor , and then compare it with the set voltage , and use the
obtained difference to drive . Control the regulating valve , and the
closed-loop control of the flow through the channel to make it
equal to the set flow .

Features

● Using the thermal principle, the mass flow of gas is not affected by changes in ambient temperature and pressure.
● Tubular shunt principle, easy to change the range and easy to install.
● Good sensor package reduces the sensitivity of external temperature changes.
● The measurement and control range is large, the maximum full scale can reach 3000ln/min
● Short warm-up time, small zero drift, high measurement and control accuracy, suitable for measurement and control of micro flow.
● It can communicate with the instrument through the secondary instrument or PLC, and the operation is simple.
● High precision: better than 1%
● Wide measurable range: 2 ~ 100%
● Fast response time, better than 3s
● Can be used for a variety of gases
● Can provide editing mixed gas calibration
