Abstract
The utility model relates to a flow metering and calibrating device, in particular to a novel flow calibrating device adopting mass method. A water inlet (2) is formed above a weighting barrel (1) and a flow diverter (3) is mounted above the water inlet (2); a water drainage pipe (4) is arranged below the weighting barrel (1) and a water drainage valve (5) is arranged above the water drainage pipe (4); and at least three high-precision sensors (6) are mounted on a base of the weighting barrel (1). After using the novel flow calibrating device, the calibrating time can be saved; precise sampling results of the high-precision sensors enable metering error to be greatly reduced; and actual total quantity of water can be reflected by the water mass no matter water flows to the bottom of the barrel or is left on the wall surface of the barrel after water is poured into the barrel; and metering data is closer to the actual condition without considering seepage loss and other factors in the prior art.
Description
Technical field
The utility model relates to a kind of flow metering and caliberating device, particularly a kind of novel mass method flow calibration device.
Background technology
Flow calibration method commonly used at present is a volumetric method, promptly build the cistern (jar) of a big volume, liquid level reading devices such as vernier or water level gauge are installed in pond (jar), flow into the water yield of cistern (jar) in the control stipulated time by timer and flow diverter, in reading the process of liquid level, to wait for that not only long time tends towards stability liquid level, and because pond (jar) easy deformation of long duration, and cause measurement result not accurate enough and then have influence on measuring accuracy.
The utility model content
For solving the defective that prior art exists, the utility model provides a kind of device that can fast, accurately carry out flow calibration.
The utility model main body is the bucket of weighing, and is provided with water inlet above the bucket of weighing, and the water inlet top is equipped with flow diverter; There is drainpipe weigh bucket below, and water discharging valve is arranged on the drainpipe; Weigh the bucket pedestal on high-precision sensor is installed, described high-precision sensor is at least 3.
During calibrational capacity, by flow diverter water is injected the bucket of weighing, and writes down water injection time simultaneously, the output by high-precision sensor obtain inject the quality of water, and with this calculated flow rate.
On above-mentioned flow diverter, be connected with the time set that can write down the flow diverter water injection time, so that write down water injection time more accurately.
In addition, at the fair water fin of installing on the described barrel inwall of weighing under the screw, the fair water fin upper end is at the water inlet place, and the lower end is near the bucket bottom of weighing.At the bottom of current directly impact barrel when preventing water filling and cause rocking of the bucket of weighing, even damage the bucket sensor at the end.
The described barrel bottom outer wall face marginal position of weighing is equipped with anti-down buttress, with too drastic the rocking even topple of the bucket that prevents to weigh.
Use flow calibration device described in the utility model, after water injection time finishes, stablize several seconds and can carry out reading, saved the nominal time greatly; The high-precision sensor collection result is accurate, and measuring error is significantly reduced; After the water filling, no matter still hang on the wall at the bottom of the flow direction bucket, can both reflect actual total amount in quality, need not consider in the prior art factors such as seepage loss, the data of measurement are more near truth.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-weigh bucket, 2-water inlet, 3-flow diverter, 4-drainpipe, 5-water discharging valve, 6-high-precision sensor, 7-fair water fin, the anti-down buttress of 8-.
Embodiment
Below further the utility model is described by specific embodiment.
In the present embodiment, the high 7.9m of bucket that weighs, external diameter 5.5m, weighing capacity 150t establishes 3 60t PR6221/60C3 type pressure transducers (precision 0.015%) on the base.
Sensor is demarcated by the qualified counterweight of measurement verification before use.
The weigh top of bucket is provided with water inlet, and water inlet below be a fair water fin, and the fair water fin screw is equipped with flow diverter down to the bucket bottom of weighing above the water inlet.There is drainpipe weigh bucket below, and water discharging valve is arranged on the drainpipe.For making things convenient for draining, the bucket bottom of weighing is made as back taper.
Carry out timing signal, flow diverter injects the bucket of weighing with water, simultaneously the opening entry water injection time; After injecting certain water gaging, switch the water (flow) direction of flow diverter and stop timing.Obtain to inject the quality of water by the output of sensor.And realize flow calibration with this.
For ease of long-time timing, flow diverter connection one can be write down the timer of flow diverter water injection time, when flow diverter begins water filling, picks up counting automatically; And when the flow diverter water (flow) direction is switched, stop timing.
Because staving is bigger, at barrel bottom outer wall face marginal position of weighing anti-down buttress is installed, to keep the stable of the bucket of weighing.
