Mass Flow Controller/Mass Flow Meter with Indicator

This mass fl ow controller/meter driven by a 24 VDC power supply has been developed as a successor to the MODEL8300.
The view point change function of the display unit and the pattern setting function are unique to this model, and noise resistance has been improved dramatically. A sister model with a detachable display and setting unit is also available.

Features

・The high-lift actuator allows this compact model to control a large fl ow rate.
・Equipped with a display and setting unit, this model can be op-erated by a 24 VDC power supply.
・The RS232C/RS485 communication function and integration function are provided as standard equipment.
・The 14-bit converter permits display and operation in 4-1/2 dig-its.
・Control of the fl ow rate of infl ammable gas is possible, because the heat generating part of the sensor is not exposed to gas.
・There are no limitations on the mounting position that may be employed.
・In addition to SV setting, fi ve other patterns can be set.
・Auto zero and auto close functions are also standard.
