DPC Differential Pressure Mass Flow Controller

March 14, 2020

DPC differential pressure/mass flow controllers are available with high maximum flow ranges of up to 1,000 L/min of gases.

 

The models simultaneously display mass flow, volumetric flow, pressure, and temperature. The DPC57, DPC67, and DPC77 are designed to control gases 200, 500, and 1,000 L/min flow ranges respectively. Standard accuracy is ± (0.5% RD + 0.2% FS). Quick (100 to 150 ms) response time is inherent.

 

Multi-Gas functionality support provides for 90 different gases and gas mixes. User-defined mixture functionality allows users to create and store up to 20 custom gas mixes with up to 5 different gases each. Optional local high contrast OLED graphic display with joystick control and Modbus RTU network interface with isolated RS485 transceiver are available.

 

Free, easy-to-use configuration and calibration software (RS-232/RS-485) and a programmable setpoint table with ramping up/down capability of up to 16 steps are included. Also, these high-flow units come with 2 programmable mass flow rate totalizers; high, low, or in-range alarms with preset action delay for mass flow, temperature, and pressure functionality.
