Multivariable Transmitters
-
The Multivariable transmitter measures and calculates the mass flow as a function of differential pressure DP as well as absolute pressure and the temperature. Therefore it should be used whenever DP flow measurement needs a compensation of temperature and pressure. The main advantage is to have just one single device in the field instead of several transmitters and a mass flow calculator.

Differential Pressure (Flow)
VEGADIF
-
In flow-rate measurement via differential pressure measurement, the differential pressure is measured with the help of a differential pressure device, e.g. an orifice plate or a dynamic pressure probe (pitot tube). The differential pressure transducer calculates the flow rate from the measured value provided by differential pressure system. Thanks to the finely graduated ranges of the measuring cells and the minimal measurement deviation, very accurate flow-rate measurement can be realized.

Ultra-thin Mass Flow Controller
DZ-100
-
The DZ-100 inherits the same CRITERION™ technology—a differential pressure detection system for laminar viscous flow ranges—used on HORIBA STEC’s MFC, the D500. This innovative technology controls the mass flow of various gases with high precision. As with the D500, the user-configurable DZ-100 supports multi-range and multi-gas applications. The compact design of the MFC reduces the internal volume of the internal gas flow path, and the optimized control algorithm improves response characteristics. It uses a compact CPU with high processing capacity, and the piezo drive circuit and control CPU are installed in the MFC module while the power supply components are housed in a separate small control box. Up to four MFC modules can be controlled by connecting them with the dedicated miniature connectors.
