Multi-Parameter Mass-Flow Controllers
The controllers simultaneously display mass flow, volumetric flow, pressure and temperature. Models DPC57, DPC67 and the DPC77 are designed to control gases at 200, 500 and 1000 L/min flow ranges, respectively. Standard accuracy is ± 0.5 percent RD +0.2 percent FS. Quick (100 to 150 ms) response time is inherent. The multi-gas functionality support provides for 90 different gases and gas mixes. A user-defined mixture functionality allows operators to create and store up to 20 custom gas mixes comprising up to five different gases. An optional local high contrast OLED graphic display with joystick control and Modbus RTU network interface with isolated RS485 transceiver are available.
