Description
Technical field
The utility model relates to a kind of Pitot bar mass flowmeter of measuring channel inner fluid mass rate.
Background technology
In prior art, mass flowmeter is the flowrate measuring tool of conventional measuring channel inner fluid mass rate.Limit by technical conditions, mass flowmeter of the prior art can only measure the mass rate that caliber is the fluids within pipes of below 300mm, corresponding mass flowmeter is not then had for the liquid mass flow of caliber in the pipeline of more than 300mm, and the cost of the corresponding mass flowmeter of the increase along with pipe diameter also significantly increases, measure the price of caliber at the mass flowmeter of the fluids within pipes mass rate of below 6mm 1-2 ten thousand yuan, measuring the price of caliber close to the mass flowmeter of the fluids within pipes mass rate of 300mm 70-80 ten thousand yuan, therefore during service property (quality) flowmeter survey big-diameter pipeline inner fluid mass rate, cost is too high, and the mass flowmeter that the caliber pipeline that reaches more than 300mm does not match.
Utility model content
The Pitot bar mass flowmeter that the technical problems to be solved in the utility model does not restrict by pipe diameter when being to provide flow mass flow in a kind of measuring channel, measurement advantage of lower cost, structure are simple and easy for installation.
For solving the problems of the technologies described above, a kind of Pitot bar of the utility model mass flowmeter, there is bi toba flow meter, this bi toba flow meter comprises bi toba flow sensor, differential pressure transmitter and flow integrator, described bi toba flow sensor has pressure head and connecting pipe, also comprise the mass flowmeter for measuring channel inner fluid density be connected with pipeline by stopple coupon, stopple coupon is equipped with drainage pump, and the signal output part of this mass flowmeter is connected with the signal input part of described flow integrator.
Adopt the Pitot bar mass flowmeter of said structure, during use, bi toba flow sensor is vertically inserted in pipeline, bi toba flow sensor flows to differential pressure transmitter the total head of the fluids within pipes extracted and static pressure signal, differential pressure transmitter flows to flow integrator the differential pressure signal of total head and static pressure, and flow integrator can calculate the volumetric flow rate of fluids within pipes, owing to also comprising the mass flowmeter for measuring channel inner fluid density be connected with pipeline by stopple coupon, stopple coupon is equipped with drainage pump, the signal output part of this mass flowmeter is connected with the signal input part of described flow integrator, drainage pump flows back in pipeline after fluids within pipes can being drained to stopple coupon again, namely drainage pump can ensure that fluids within pipes flows through stopple coupon effectively, mass flowmeter can measure the density of stopple coupon inner fluid, according to the volumetric flow rate of fluids within pipes and the density of fluid, the mass rate of fluids within pipes can be drawn.Mass flowmeter in the utility model is the density indirectly being recorded fluids within pipes by the density of measurement stopple coupon inner fluid, impact not by pipe diameter size when therefore measuring, and the diameter of stopple coupon can be accomplished very little, greatly can reduce the measurement cost of the mass rate of measuring channel inner fluid like this, the utility model introduces stopple coupon, drainage pump on the basis of bi toba flow meter, and structure is relatively simple and easy for installation.
Improve as one of the present utility model, described stopple coupon has water inlet pipe and return pipe, the bottom of water inlet pipe and return pipe has water inlet and water return outlet respectively, described water inlet pipe and return pipe pass described connecting pipe from top to bottom and stretch out from the bottom of connecting pipe, the sealing of described mass flowmeter is loaded between the water inlet pipe and return pipe on described connecting pipe top, described drainage pump be arranged on be positioned at connecting pipe top water inlet pipe on.Adopt and be actually a stopple coupon after said structure and bi toba flow meter is organically fused into one, stopple coupon becomes a part for connecting pipe, makes installation of the present utility model more convenient.
Improve as another kind of the present utility model, described stopple coupon is U-shaped, the both sides of U-shaped stopple coupon have water inlet for being connected with pipeline diapire and water return outlet respectively, described mass flowmeter sealing is loaded on the base of U-shaped stopple coupon, and described drainage pump is arranged on the stopple coupon between mass flowmeter and water return outlet.Adopt the utility model after said structure when mounted, two holes corresponding with stopple coupon both sides separately need be opened on pipeline, adopt said structure the utility model has the advantages that be no matter drainage pump in bi toba flow meter or stopple coupon or mass rate in respect of fault time, can keep in repair separately, do not need the utility model entirety to take off, be conducive to operation and maintenance of the present utility model like this.
As further improvement of the utility model, the caliber of described stopple coupon is at below 6mm.The caliber of stopple coupon, at below 6mm, can make the cost of the mass flowmeter matched with it very low, reduce manufacturing cost of the present utility model on the whole.
