1、 Overview

Intelligent integrated vortex flowmeter is a volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the Karman vortex principle. And it can be used as a flow transmitter for vortex flow meters in automation control systems.

This instrument adopts advanced differential technology, combined with isolation, shielding, filtering and other measures, to overcome the problems of poor seismic resistance and small signal data disorder of similar products. It also adopts unique sensor packaging technology and protective measures to ensure the reliability of the product. There are two types of products: basic type and composite type. The basic type measures a single flow signal; The composite type can simultaneously measure temperature, pressure, and flow rate. Each type has a whole or split structure to adapt to different installation environments.

2、 Characteristics and Applications of Instruments

characteristic:

No movable parts, long-term stability, simple structure for easy installation and maintenance

Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance

7、 Comparison Table of Sensor Sizes for Vortex Flow Meter

explain:

When measuring steam, the total height of the sensor is H+100mm;

Card mounted sensors must be equipped with dedicated 2.5MPa or 4.0MPa concave flanges;

The outer diameter D of the flange type is the outer diameter of the flange with a nominal pressure of 2.5 MPa, which is matched with the flange according to the JB80-51 standard.
