Kaifeng AFT Instrument CO.,Ltd products

AFTLD/D battery-powered electromagnetic flow meter converter using internal battery supply no need external power supply ,it is suitable for wild power grid which can not arrive and power grid laid the operation of the difficult situation,especially suitable for tap water system monitoring,measurement and installment .AFTLD/D battery-powered electromagnetic converter using low power consumption circuit technology design ,reliable,efficient excitation,signal processing circuit implementation measurement function,ensure has high reliability and stability of the converter ,and adopt efficient system management technology greatly reduced the system power consumption ,save power costs at the same time achieve precise measurement.

Measurement is not affected by the variation of flow density, viscosity, temperature, pressure and conductivity. High accuracy measurement is guaranteed according to the linear measurement principle. No obstacle in the pipe, no pressure-loss and lower requirement for straight pipeline.DN 6 to DN2000 covers a wide range of pipe size. A variety of liners and electrodes are available to satisfy different flow characteristic.

The throttling part of Type V inner cone flowmeter is a conical body which is spending in the center of pipeline ,it can improve the flow fluid ,the high pressure Pi from tube wall which is the flow body has not yet throttling accelerated before vertebral devices ;Low pressure P2 are taken from the after centrum rear ,and it can draw forth transmitter branch pipe in front of inner vertebral ,its square root of differential pressure (P1-P2)is proportional to the rate of flow ,then work out a fluid flow,the products are widely used in flow measurement for the liquid ,gas or steam of the steel industry ,electric power ,chemical etc industry.

 Standard orifice plate is one product of the throttle device which has simple structure 

LUGB-type 2 vortex flow meter measuring in the flow of liquid of steam ,gas and low viscosity according to Carmen and Struhal relavant spiral produce and on the theory of the relationship .As show in picture ,In the meter body vertical insert a triangular prism root namely the happening of the body,when eddies of medium flow through the table body, in triangular prism behind the alternate produce in opposite directions regular karman swirl ,its spiral separation and the flow of the medium frequency F speed by head is proportional to the V detected the number of spiral ,can measure the flow velocity,again according to the table body mouth

Ultrasonic flow meter  is designed to work with clamp-on transducers to enable the flow of a liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts through the pipe wall or protrude into the flow system. Using ultrasonic transit time techniques the is controlled by a micro-processor system which contains a wide range of data that enables it to be used with pipes with an outside diameter ranging from 15mm up to 6000mm (depending on model) and constructed of almost any material. The instrument will also operate over a wide range of fluid temperatures.

Coriolis mass flowmeters are the leading precision flow and density measurement solution offering the most accurate and repeatable mass measurement for liquids or slurries. AFT meters offer the most accurate measurement available for virtually any process fluid while exhibiting exceptionally low pressure drop.

LWGY series Turbine flow meter draw the leading technology integrating with advanced design to produce the new generation of turbine flowmeter with the features of simple structure, light weight, high accuracy, good repeatability, flexible reaction, convenient installation/maintenance/application etc..  It is widely applied to measuring the liquid of which kinematic viscosity is under 5*10-6㎡/s and have no impurify of fibre,grain etc.,and no corrosive interaction with the stainless steel 1Cr18Ni9Ti,2Cr13,and A12O3, and hard alloy in seal pipes. The liquid of kinematic above 5*10-6㎡/s can be measured after real liquid calibration of flowmeter.  It can be used in value control,  siren when excess, if co-ordination with special display instrument. So it is the ideal instrument of measuring flow value and saving energy.
