Thermal mass flow meters

The Smart series of thermal mass flow meters provides a variety of self-diagnostic and field-adjustment features, as well as the ability to confirm or "field-validate" the meter`s calibration and measurement accuracy in the field. The microprocessor-based transmitter integrates the functions of flow measurement, flow-range adjustment, meter validation, and diagnostics in a compact, explosion-proof housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter`s 2 ? 12 backlit LCD panel. The programmable transmitter is easily configured via an RS-232 com port and Smart Interface PC-based software, or via the display and membrane switches on the front panel of the device. The meters allow easy configuration or changing of the following parameters: Flow range, totalizer, alarm settings, time response, zero flow cutoff, and a calibration correction factor to compensate for flow profile varations or specific application conditions.
