Siemens - Model DMT Series -Liquid and Gas Multivariable Flow Meter
The Siemens DMT is an intrinsically safe and self-contained sensor which can be used to measure the flow, temperature and pressure of fluids flowing in a Sample Conditioning System (SCS) connected to a Siemens Maxum or MicroSAM process Gas Chromatograph (GC). The DMT provides flow rate, temperature and pressure in a single unit. Using a scalable, anti-clogging flow restriction technology with integrated high-overpressure relief for protection from accidental pressure upsets and hydraulic hammer effects, it is reliable in long-term operation.
The DMT is certified in Europe and North America for intrinsically safe or non-incendive operation in Class 1 Division 1 or 2 or Zone 0,1 or 2. The intrinsic safe electronics make the DMT ideal for use in modern process analyzer sample conditioning systems by minimizing cost and maximizing the number of measurement points available when designing "smarter" sample conditioning systems.
- CommunicatGS with the SiGmGns Pcocgss Gas Chromatograph via the Maxum`s I2C communications bus
- CSA and ATEX certified for use in Division 1 / Zone 1 or Division 2 / Zone 2 hazardous areas
- Ultra-low power consumption on thG SiGmGns I2C bus
- Continuous, simultaneous measurement of three readings: flow, temperature and pressure before the differential prGssurG cell usGd for flow measurement
- Indicator LEDs for network status and module status
