Abstract
The utility model relates to a forward-inverse bidirectional measuring bending pipe flowmeter, comprising a pipe, a bending pipe flowmeter, a flow direction discriminating device and a secondary measuring instrument, the bending pipe flowmeter and the flow direction discriminating device are adjacent to each other and positioned on the pipeline and are respectively connected with the secondary measuring instrument, the bending pipe sensor is characterized in two-way measurement, by adding the flow direction discriminating device, and matching with the secondary measuring instrument with forward-inverse bidirectional measurement performance, the utility model realizes to measure in forward-inverse bi-direction, saves a set of measuring device, facilitates the economic calculation of suppliers and buyers, broadens the application field of the pipe bending flowmeter, and achieves the measuring requirement that is not able to be finished by other flowmeters.
Description
Technical field
The utility model relates to a kind of flow measurement device, refers in particular to a kind of positive and negative bidirectional measuring type elbowmeter.
Background technology
Elbowmeter is a kind of more novel flow measurement device, flow in can pipeline and be not subjected to the influence of direction of flow, but which side convection cell specifically do not have decision-making function to flowing to, therefore, aligning reverse flow when all needing to measure separately, it is unable to do what one wishes just to seem.During commercial Application, owing to be subjected to the influence of season, output and position, FLUID TRANSPORTATION source, the situation that the fluid in the pipeline flows with positive and negative two way alternate happens occasionally.Independent accounting and cost control require to measure the flow of all directions clearly, therefore, only can't address this problem with a flowmeter under the prior art condition.
Summary of the invention
The purpose of this utility model provides a kind ofly can carry out the elbowmeter of positive and negative bidirectional measuring to the pipeline inner fluid, thereby saves a cover measuring apparatus, helps the accounting of both sides of supply and demand.
Technical solution adopted in the utility model is: a kind of positive and negative bidirectional measuring type elbowmeter, comprise pipeline 1, elbowmeter 2 and secondary measurement instrument 4, and also comprise flowing to discriminating gear 3.Elbowmeter 2 and flow to discriminating gear 3 adjacent being installed on the pipeline 1, and be connected with secondary measurement instrument 4 respectively.
Flow to discriminating gear 3 and be made of throttling element 31 and differential pressure transmitter 32, throttling element 31 is installed on the pipeline 1 and by connecting pipe and is connected with differential pressure transmitter 32.
The beneficial effects of the utility model are: be used for being equipped with Bending Tube Sensor and flow to discriminating gear on pipeline, elbowmeter and flow to discriminating gear and can when measuring flow, measure and flow to, and show by the measurement data of secondary measurement instrument 4 with different directions, make bidirectional measuring save a cover measuring apparatus, remarkable in economical benefits helps the business accounting of both sides of supply and demand simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
Positive and negative bidirectional measuring type elbowmeter as shown in Figure 1, a kind of positive and negative bidirectional measuring type elbowmeter comprises pipeline 1, elbowmeter 2 and secondary measurement instrument 4, also comprises flowing to discriminating gear 3.Elbowmeter 2 is installed on the pipeline 1, flows to discriminating gear 3 and is separated by more than 5 times of pipe diameters apart from the adjacent that is installed in pipeline 1 with elbowmeter 2.
Flowing to discriminating gear 3 is made of throttling element 31 and differential pressure transmitter 32, throttling element 31 is installed on the pipeline 1, the different differential pressure value that the medium that different directions flows through forms by throttling element 31, record by differential pressure transmitter 32, according to the sequencing of the positive and negative differentiation tube fluid that records differential pressure value, thus the differentiation that flows to.
Claims (3)
