Product Description

Part One: Introduction
Metal tube flowmeter consists of measuring tube, float, indicator and process connection components with the characteristics of small size, wide measuring range, and 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.

There are local indicators and smart remote types. For the local type, needles pointer shows instant flow. For the LCD type, needles pointer shows instant flow. The instant flow and the accumulative flow are digitally shown on the LCD display. For the smart remote type, there are many kinds of outputs, such as upper-lower limit alarming output, pulse output, standard two-wire 4-20mA current output, and HART communication protocol and so on.

Smart remote metal tube flowmeter adopts advanced 16-bit microprocessor, high accuracy sensor, SMD elements and high quality industrial components to guarantee the excellent performances of this flowmeter after the signal processing technology of digital filtering and software calibration.

According to different process connection methods, metal tube flowmeters are divided into many inflow-outflow types, such as bottom inflow& top outflow type, left inflow&right outflow, right inflow&left outflow and so on. Customer can choose the measuring tube needed according to its requirements. Due to its excellent performance, reliability and competitive price, it is widely used in the fields of oil, chemical industry, steel manufacture, light industrial, water etc. Metal tube flowmeter takes many different materials and is suitable for flow measurement of all non-corrosive, corrosive and strong corrosive mediums.

Part Three: Working principle

  Measured medium flows through the space between measuring tap pipe and float from bottom to top, producing differential pressure on the top and bottom of float to form lifting force. When the lifting force on float is stronger than the weight of float in the fluid, the float will rise, annular area will also increase, the flow rate of fluid at annular space will suddenly decrease, the differential pressure on top and bottom of float decreases, the lifting force on the float also decrease till lifting force and the weight of float keep balance, float will stay at a location. The height of float is the flow of measured medium. There's magnetic steel in the float, while float moves up and down with medium, magnetic field will change with the movement of float. The matchup of float's flow between the float in the tap pipe and the flow passing annular space:
