In the Chinese patent that application number is " 201120024370.0 ", disclose the utility model patent that a kind of name is called " a kind of metering device with wide measuring range ", comprised flowmeter, water inlet pipe, rising pipe, operation valve, inlet triplet for water pipe adapter, outlet three way pipe adapter, auxiliary water inlet pipe, auxiliary rising pipe, auxiliary flow meter and aux. control valve.Although it can meet the metering occasion of various flow range,, can't resolve the sticking problem of dirty fluid, cause the measuring accuracy of flowmeter to decline, and need frequent dismounting and cleaning dirt, cause unnecessary loss.
Utility model content
In order to address the above problem, the utility model provides a kind of measuring apparatus, and its stable working is reliable, measuring accuracy is high, sturdy and durable, easy to install and use, the advantage such as range coverage is large, meanwhile, also solve small-range and do not measured or measured inaccurate problem.
A kind of measuring apparatus, comprise the upstream three-way, main flow meter, main flow control valve and the downstream threeway that connect successively with direction of flow, between upstream three-way and downstream threeway and be connected with secondary flow amount and take into account secondary flow control valve, described auxiliary flowmeter is electrically connected by interface signal line and main flow meter, is connected with filtrator at the front end of upstream three-way.
Further, described auxiliary flowmeter one end is ganged up and is connected with described upstream three-way by the other pipe in upstream and auxiliary pipeline, and the other end is connected to secondary flow control valve, the other pipe in downstream, auxiliary pipeline successively, and gangs up and be connected with downstream threeway.
Further, described main flow meter and main flow control valve are electrically connected by main valve drive wire.
Further, described auxiliary flowmeter and secondary flow control valve are electrically connected by auxiliary valve drive wire.
The utility model has the advantage of: (1), by adopting filtrator effectively to prevent the adhesion of dirty fluid, has eliminated the whirlpool producing when fluid is flowed through flow measurement element to a certain extent, makes stable signal transmission improve measuring accuracy; (2) adopt the collocation of main flow meter and auxiliary flowmeter to use, can adapt to the metering in the field that flow range fluctuation is very large; (3) main flow is taken into account auxiliary flowmeter and is electrically connected by interface signal line, has realized two flow meter collocation flexibly, freely switches use between the two according to measuring requirement; (4) two flowmeters, respectively by being electrically connected with flowrate control valve, have ensured accuracy and the accuracy of flowmeter metering; (5) flow apparatus metering covering range ability is large, and auxiliary flow meter has solved low discharge and do not measured or measure an inaccurate difficult problem simultaneously.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of metering device with wide measuring range structural representation.
Embodiment
The utility model provides a kind of metering device with wide measuring range, can meet the metering in the very large situation of measures range fluctuation, meanwhile, has also solved small-range and has not measured or measure inaccurate problem.
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described, obviously, described is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
Shown in Fig. 1, a kind of metering device with wide measuring range, comprise the filtrator 1 connecting successively with direction of flow, upstream three-way 2, main flow meter 3, main flow control valve 5 and downstream threeway 6, between upstream three-way 2 and downstream threeway 6 and be connected with secondary flow amount meter 7 and secondary flow control valve 10, described auxiliary flowmeter 7 is electrically connected by interface signal line 8 and main flow meter 3, described auxiliary flowmeter 7 one end are ganged up and are connected with described upstream three-way 2 by the other pipe 12 in upstream and auxiliary pipeline 11, the other end is connected to secondary flow control valve 10 successively, the other pipe 13 in downstream, auxiliary pipeline 11, and gang up and be connected with downstream threeway 6, described main flow meter 3 is electrically connected by main valve drive wire 4 with main flow control valve 5, described auxiliary flowmeter 7 is electrically connected by auxiliary valve drive wire 9 with secondary flow control valve 10.
