Description
Technical field
The invention belongs to water pump relevant device field, more particularly to a kind of ultrasonic flowmeter with positioning function.
Background technology
Ultrasonic flowmeter is a kind of by detecting effect of the fluid flowing to supersonic beam (or ultrasonic pulse) to measure stream
The instrument of amount, mainly by mounted on ultrasonic transducer (or the ultrasonic flow rate being made of energy converter and measurement pipe measured on pipeline
Sensor) and converter composition.Ultrasonic flow instrument be with " speed difference method " be principle, measure pipe in fluid flow instrument
Table.It uses advanced multi-pulse techniques, signal digital processing technology and error correcting technique, and flow instrument is made to be suitable for work
The environment at industry scene, metering are more convenient, economical, accurate.Product reaches domestic and international advanced level, can be widely applied to oil, changes
The fields such as work, metallurgy, electric power, plumbing.
The mounting means of ultrasonic flowmeter in a general case there are two types of, be respectively V-type installation and Z-type installation.
The pipeline of V methods DN15mm-200mm preferentially selects V methods, by external-clamping type ultrasonic flowmeter two sensors water when installation
Flat alignment, center line is parallel with conduit axis, and pays attention to the direction of the launch centainly opposite (two sensor orientations are inwardly).
V methods have it is easy to use, measure accurate feature.It is higher less than the Pipe installing precision of DN50mm for bore, it is noted that letter
Number intensity, signal quality, transmission time are than these parameters.
The pipeline of DN200mm-6000mm preferentially selects Z methods, also can be selected when V methods do not detect signal or poor signal quality
Z methods.It is allowed when installation between two sensors and is equal to mounting distance along the vertical range of tube axial direction, and ensure two sensors
On same axial plane, and pay attention to the direction of the launch centainly opposite (two sensor orientations are inwardly).Since Z methods are that ultrasonic wave exists
Medium is directly received and dispatched in propagating, and signal does not reflect, thus signal intensity attenuation is minimum.So Z methods have, signal strength is high,
Feature reliable for operation.However, the ultrasonic flowmeter installation of Z methods installation at present is inconvenient, installation error is very big.
Invention content
Technical problem：In order to solve the defects of prior art, the present invention provides a kind of ultrasonic waves with positioning function
Flowmeter.
Technical solution：A kind of ultrasonic flowmeter with positioning function provided by the invention, including probe fixed plate, one
To rigid measuring scale, sliding rail restraint zone, flow-meter probe；The pair of hardness measuring scale is respectively arranged at a left side for probe fixed plate
Right both sides, and a pair of rigid measuring scale and probe fixed plate are fixed together using sliding rail restraint zone；The probe fixed plate
It is equipped with sliding rail, the flow-meter probe is set in probe fixed plate and can be horizontally slipped along sliding rail by sliding rail.
Advantageous effect：Structure of ultrasonic flowmeter provided by the invention is simple, of low cost, easy to use, by visiting
The rigid measuring scale of the front and back setting of head fixed plate, is measured using rigid measuring scale, ensures that sliding rail is substantially parallel with water pipe, to significantly
Installation accuracy is improved, ensure that measurement accuracy.
Description of the drawings
Fig. 1 is the structural schematic diagram of the ultrasonic flowmeter with positioning function.
Specific implementation mode
There is the ultrasonic flowmeter of positioning function to further illustrate the present invention below.
Ultrasonic flowmeter with positioning function is shown in Fig. 1, including probe fixed plate 1, a pair of rigid measuring scale 2, sliding rail
Restraint zone 3, flow-meter probe 4；A pair of of hardness measuring scale 2 is respectively arranged at the left and right sides of probe fixed plate 1, and utilizes sliding rail
A pair of rigid measuring scale 2 and probe fixed plate 1 are fixed together by restraint zone 3；Fixed plate 1 of popping one's head in is equipped with sliding rail 5, flowmeter
Probe 4 is set in probe fixed plate 1 and can be horizontally slipped along sliding rail 5 by sliding rail 5.
When Z methods are installed, need the ultrasonic flowmeter with positioning function using a pair of of present invention, method as follows：
(1) what a flow-meter probe 4 is installed respectively in pipeline opposite sides relative position：Utilize a pair of rigid measuring scale
2 amounts wait for the outer diameter of water gage glass, determine 5 position of sliding rail in probe fixed plate 1 using a pair of rigid measuring scale 2, make sliding rail 5 and water
It manages parallel, then so that probe fixed plate 1, a pair of rigid measuring scale 2 is fixed on water pipe lateral wall with sliding rail restraint zone 3；
(2) flow-meter probe 4 is slided into downstream position, you can complete accurate installation upstream flow-meter probe under
Swim flow-meter probe.
