ADMAG CA Magnetic Flow Meter
Brand: Yokogawa Electric CorporationThe ADMAG CA magnetic flow meter adopts a system to pick up the electromotive force generated in a fluid by electrodes provided outside a ceramic pipe through the capacitance of the pipe.
In addition, the flow meter employs a prominent high-frequency excitation method that reduces flow noise in low conductivity fluid.
ADMAG CA magnetic flow meter is excellent at measurement in ultra-low conductivity fluids down to 0.01 microS/cm, adhesive fluids, or slurry fluids.
Since ADMAG CA employs a non-wetted electrode construction, picking up the signal voltage by electrode plates provided outside a ceramic pipe through the capacitance of the pipe.
Features- Ultra Low Conductivity Measurements
- Capacitance type electrodes and very high impedance amplifier of ADMAG CA makes ultralow conductive fluid measurement possible. This combined technology allows the ADMAG CA to measure fluids with conductivity levels as low as 0.01μS/cm.
- Accuracy Specification
- The ADMAG CA offers accuracy up to 0.5% of flow rate.
- Non-wetted Electrodes
- The ADMAG CA utilizes a non-wetted electrode design. Instead, electrode pickup plates are placed on the measuring tube to pick up and measure the electromotive force. The non-wetted electrodes create an excellent opportunity for use in chemical and slurry applications as it is not affected by the corrosion, coating, ultra-low conductivity, and abrasive issues associated with wetted electrodes.
- This reduces the effect of slurry or process noise, eliminates potential leak paths, and makes it ideal for high coating process applications.
- Ceramic Liner - Excellent for Corrosive Fluid and Abrasive Fluid
- Ceramic liner tubes have many advantages over fluoropolymer (PFA/PTFE) or other liner materials like rubber. ADMAG CA uses alumina ceramic (Al2O3 ) for its ceramic liner tubes, which demonstrates excellent characteristics for a broad range of applications.
- The alumina ceramic (Al2O3 ) used in the ADMAG CA has a purity of 99.9%.
- Resistance to abrasion, ensuring accurate measurements even with highly abrasive slurries
- Resistance to corrosive fluids
- Durability under high temperature and high pressure conditions without additional metal tube
- Coating Resistant
- Non-wetted capacitive electrodes can measure electromotive force through capacitance including coating insulating material, offering steady measurement. The ADMAG CA is ideal for field-proven applications such as latex, reclaimed oil, hot spring water, red mud, and dye which are more difficult to measure with conventional magnetic flow meters.
- Mirror Finished Surface
- By means of a special magnetic polishing process, the inner surface of the ceramic liner tube can be given a mirror finish. This polishing method is advantageous in eliminating problems such as abrasive irregularities and dull edges and will reduce the coating affects of your process. The mirror finished ceramic liner tube has a surface roughness of Ra 0.1 μm.
