The new DMS-Series KOBOLD digital mass flow meters and mass flow regulators have been specially developed for use in gas measurement, where excellent accuracy, high reliability, robust casing, stainless materials and maximum flexibility are important. The six keys on the control panel and the graphic display make the meter easy to use. The display unit, full scale value of the measuring range, the valve function and the desired value can be set in the simple menu structure.
The second analogue output can be selected as 0 - 5 V DC , 0 -10 V DC or 1 - 5 V DC. If the medium changes, the corresponding gas can simply be selected. The memory stores the parameters of ten gases, and they can also be programmed off standard. A password protects the  configuration against unauthorised access. The electrical connection is made with a Sub-D plug. Optionally, the control panel can be connected with a RJ45 plug and socket connection.
A special RCA connector is required for the RS232 interface. Compared with float flow meters, the DMS mass flow meter has neither moving parts, nor is it necessary to compensate for changes in operating conditions such as pressure and temperature, because here the mass flow is being measured. The measuring instrument can be installed in practically any position and the  simple mechanical construction provides the  highest degree of reliability, both with the use of aggressive gases, and also in raw industrial operation.
