阿美特克AMETEK超聲波液位變送器的詳細資料

阿美特克AMETEK超聲波液位變送器

Overview

A new family of Ultrasonic technology products offers a 2-wire and line powered version for non-contact level measurement of liquids and slurries for level, distance, volume and open channel flow.

• Patented SMART GAIN™ circuitry automatically ignores false echoes from internal tank obstructions and agitator blades without adjustment

• Superior accuracy – 0.15% of measuring range up to 30 ft

• 2-wire HART intrinsically safe or explosion proof, suitable for Class 1, Division 1, hazardous locationss
