Electromagnetic Flowmeter
This new model, at high performance solutions, both as hardware and software, can be defined as an HI-TEC line, addressed to very demanding customers from the point of view of performance and precision.
Output signal is both analogical and digital; and qualitatively the instrument is very performing, having accuracy < +-0,5% of reading and repeatability of 0,1% r.v.
ASAMAG is also good to be used with any liquids with conductivity better than 5 μS/cm; they are insensitive to temperature and pressure variations, density or viscosity of process fluid.
ASAMAG advantages are:
- maximum control (also in remote). ASA can provide also a serial interface software usable by PC and the port RS232 (or RS485) of the converter, making possible the visualization and the modification of process parameters.
- all ASAMAG are equipped with Sensoreprom unit that contains all calibration data of sensor tube and all the settings of converter for the lifetime of the product. Fabrication parameters and instrument size are recordered inside the Sensoreprom together with the working parameters set by customer. In the event of tube substitution, Sensoreprom make it very easy and rapid.
- great flexibility is intended as the chance to have compact or remote version with the same measuring tube and converter.
For a complete electromagnetic flowmeter you have to combine ASAMAG converter with sensor tube of Flanged, Wafer or DIN-Clamp-Gas model.
