The FH20xx electromagnetic flow meter is intended for flow-rate measurements of conductive liquids, such as water, wastewater, slurries, and other conductive liquids. The FLONET FH20xx is suitable for use in water and heat supply systems, chemical, food processing, and other industries. They meet the most stringent requirements on measurement accuracy, long-term stability and hygienic standards. Flow-rate measurements in both directions of flow are possible.
The meter sensor has no movable mechanical parts and its inclusion in the piping system will have no effect on the hydraulic or pressure flow conditions. The converter unit provides for sensor energizing and processing of the sensor signals. The meter has pulse and current outputs, as well as an interface to the HART communication protocol.
Application| Application Area | Details |
|---|---|
| Measurement Purpose | Measures the volume flow rates of electrically conductive liquids in closed piping systems. |
| Flow Direction | Measurements can be done in both flow directions. |
| Measurement Accuracy | High measurement accuracy over a wide range of flow rates (0.1 to 10 m/s / 0.33 to 33 ft/s). |
| Liquid Conductivity | Minimum required conductivity of the measured medium is 5 µS/cm. |
| Transmitter Functionality | Microprocessor-controlled FLONET FH20xx transmitter processes measurement data and displays/transmits results. |
| Communication | Supports the HART® protocol (optional). |
| Configuration | Basic settings are factory-set. User-definable settings for data processing, analysis, display, and output are protected by a password. |
