Description
Technical field
The utility model belongs to ore pulp-measuring and fluid calculation technical field, and in particular to a kind of pulp conveying metering dress
It sets.
Background technique
Currently, mainly flowmeter is used to carry out quick metering ore pulp-measuring, flowmeter is mainly ultrasonic flowmeter,
Time difference type and Doppler type can be divided by measuring principle point, ultrasonic flowmeter is propagated in flow media based on ultrasonic wave
Speed is equal to the principle of the mean flow rate of measured medium and the geometry sum of sound wave speed itself and designs.It is also by velocity measurement
To reflect uninterrupted.It receives extensive attention and makes in recent years using the transit time ultrasonic flowmeter that time difference type principle manufactures
With being a kind of most commonly used ultrasonic flowmeter of current enterprises and institutions.The ultrasonic Doppler flow manufactured using Doppler effect
Meter is chiefly used in measuring medium and has certain suspended particulate or bubble medium, using there is certain limitation, but solves the time difference
Formula ultrasonic flowmeter can only measure the problem of single clear fluid, be also considered as the ideal instrument of non-cpntact measurement two-phase flow
Table.Ultrasonic flowmeter used at present has the disadvantage that the temperature measurement range of 1) ultrasonic flowmeter is not high, general
