Why it is specified
Flow and level are where a plant discovers that the instrument was chosen for the line size instead of for the medium. Conductivity, viscosity and solids all get asked before a selection is issued.
Typical applications
- Batch and totalising measurement
- Cooling water balance
- Dosing verification
- Tank level indication
Options and executions
- Empty pipe detection
- Factory flow calibration certificate
- Hygienic connections and finish
- Remote transmitter with a 10 m cable
