Detailed Description
Roots Flowmeter
Overview
LL Roots Flowmeter has two types: one is a traditional mechanical meter, the other is a mechatronic electronic meter. LLE Intelligent Roots Flowmeter (hereinafter referred to as the meter) is a new type of intelligent mechatronic volumetric flowmeter, it is our patent product. It absorbs the advantage of high measuring accuracy of volumetric flowmeter, and the internal error correction of system performed by the microcomputer, in order to achieve series production of high accuracy flow meters. Except the error compensation to mechanical system, LLE Intelligent Roots Flowmeter can also increase the temperature compensation, pressure compensation and other functions according to the users’ requirements.
Operating Principle and Structure
LL Roots Flowmeter consists of a waist-wheel transmitter and a counter. The principle of it is taking input and output pressure difference of a pair of waist-wheels in transmitter as the driving force, making rotary motion in the metering chamber, in the process of rotating, when one of the waist rotates to a position that the major axis is parallel to the import and export, two waist-wheels and two end caps as well as side walls of the metering chamber forms a closed measuring chamber, to calculate the volume of liquid in metering chamber, will get a constant quantity, as the basic measurement of the transmitter. Measurement equivalent and accumulation of revolutions of the waist-wheel in unit time are the flow value of transmitter. Display the flow though counter.
