193 MEASURING RANGE AUTOMATIC FLOW METER / ULTRASONIC-VORTEX FLOW METER ASUSV SERIES ULTRASONIC-VOLTEX FLOW METER ASUSV SERIES . THE WETTED PART IS MADE OF CORROSION-RESISTANT ALL-PLASTIC MATERIAL (ANTI-CORROSIVE RESIN), MAKING THE METER IDEAL FOR CHEMICAL SOLUTION LINES FOR CHEMICAL, STEEL, ELECTROLYSIS, SEMICONDUCTOR AND PURIFICATION FACILITIES. . STABLE AND HIGHLY ACCURATE FLOW MEASUREMENT WITH AN ACCURACY OF +/-1.0% (RD). . KARMAN VORTEX DETECTION USING ULTRASONIC SENSOR PROTECTED FROM THE EFFECTS OF MECHANICAL NOISES SUCH AS PIPE VIBRATION. NOTES To maintain the measurement accuracy, provide a straight pipe of 10D on the upper-flow side and of 5D in the downstream.
