4-20ma Hart Signal Output Air & Liquid Rotameter
Metal rotameter consists of measuring pipe, float, indicator and process connection components with the characteristics of small size, wide measuring range, easy installation. In the industry area, it is widely used to measure flow of gas, liquid, and steam, especially suitable for mediums with low current velocity and low flow rate.
