DB05 Thermal mass flowmeter and controller for gases

The DB05 thermal mass flow meter and controller is a modu­lar measuring system for measuring and controlling the mass flow of gases. The device is optionally available as a pure flow meter or with integrated control valve with PI control behav­iour.

As standard, the DB05 contains analogue current or voltage signals for the instantaneous flow rate and, in the controller function, an analogue input for setpoint specification. A mea­sured value display is available as an option. A variety of non-aggressive gases with measuring ranges from 0...25 ml/min to 0...450 l/min can be measured.

Due to the modular design, the position-independent installa­tion and the simplest cleaning without recalibration, the DB05 can be used for a wide variety of applications such as analyti­cal instruments, in the semiconductor industry, for com­pressed air systems, lasers, welding systems or fuel cells. Depending on the application, the instrument can be supplied with an aluminium or stainless steel housing and with a stan­dard accuracy of 1 % or as a precision instrument with 0.3 % accuracy.
