About flowmeter, what is mechanical flowmeter, is a specific flowmeter
Ultrasonic flowmeter is specially used to measure the flow of liquid in the pipeline. It is usually used in large diameter. The ultrasonic heat meter is used to measure the heat in the pipeline. It consists of three parts, the flow measuring device, the temperature measuring device and the microcomputer. Among them, the flow metering device is an ultrasonic flowmeter.
Generally speaking. Ultrasonic is a way of measuring flow, relative to mechanical type.
Differential pressure type flowmeter has the advantages of simple structure, working principle and clear, can be directly using the Bernoulli equation and the continuity equation derived flow equation, and the installation is convenient, the accumulation of a large number of reliable experimental data, differential pressure flowmeter is installed on the differential pressure and flow rate according to the measuring element in the pipeline known fluid conditions and measuring element and pipe geometry to measure the flow meter. A differential pressure flowmeter consists of a primary unit, a measuring element, and two differential pressure conversions and flow meters. The differential pressure flowmeter measuring element type on the classification, such as orifice flowmeter, Venturi tube flowmeter and pitot tube flowmeter, the two device for a variety of mechanical, electronic, mechanical and electrical integration type differential pressure gauge, differential pressure transmitter and flow calculation and display instrument has been developed for a large class of instrument specifications ridge complex, differential pressure according to the principle of the meter measuring element can be divided into: throttle, dynamic pressure head, hydraulic resistance type, centrifugal type, dynamic pressure gain and jet and other categories, the throttle and the dynamic pressure head is the most widely used.
