?the beneficial effects of the utility model:
The utility model is simple in structure, swift and convenient to operate, calibrating accurately, reliably, the design safety of liquid level gauge manufactures and designs according to < < JJG971-2002 liquid level gauge vertification regulation > >, can be calibrating magnetic flap level gauge, floating ball lever meter, pressure-type liquidometer, radar level gauge, ultrasonic level gages etc. provide stable liquid level demand, can liquid level be realized and automatically being controlled and accurate adjustment, is furnished with the long steel plate rule of 0.5mm or 1mm resolution 2000mm, can examine and determine the liquid level gauge fathoming below 2000mm.
Accompanying drawing explanation
Fig. 1: the utility model structural representation.
Wherein: detect water tank 1, plexi-glass tubular 2, cistern 3, water level controller 4, glass-tube liquid level meter 5 and master scale chi 6.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model.
As shown in Figure 1, a kind of liquid level meter detecting device, mainly forms by detecting water tank 1, plexi-glass tubular 2, cistern 3, water level controller 4, glass-tube liquid level meter 5 and master scale chi 6.Cistern 3 is connected with detection water tank 1 by pipeline, detect on water tank 1 glass-tube liquid level meter 5 and water level controller 4 are installed, water level controller 4 is connected with import protected type water pump, detect water tank 1 bottom and be provided with rapid-acting coupling connection, described detection water tank 1 side is provided with plexi-glass tubular 2, on plexi-glass tubular 2, be fixed with master scale chi 6, master scale chi 6 permissible errors are positive and negative 0.35mm, and described plexi-glass tubular 2 is connected with glass-tube liquid level meter 5 and detection water tank 1.
Detect water tank 1 and cistern 3 and be all furnished with heavy caliber cleaning blowoff valve, when being convenient to keep in repair at ordinary times, carry out operation.Plexi-glass tubular 2 is fixed on and is detected on water tank 1 by cable and nut, by nut, connect and plexi-glass tubular integral body can be fallen, to solve the inadequate problem of vertical space, plexi-glass tubular is of a size of height 2000mm, diameter 200mm, organic glass top is reserved with the hole that diameter is 60mm, for examining and determine radar, ultrasound wave, ball float and called putting-into-type liquid level meter.
The utility model course of work:
Preliminary work before calibrating, detects whether level of water tank base and organic glass pipe holder with level meter inspection, and adjusts to optimum condition;
Install, adjust detected liquid level gauge, fetch boiling water on level controller " positive stroke water pump control knob " numerical value is shown to numeral is adjusted into 50.0cm, when water level rises to 50.0cm, water pump quits work, Deng liquid level steadily after, whether observe detected liquid level gauge water level value just in time at 50.0cm, if lower than, can start water pump water adding by point driving switch, if higher than, open revesal inching switch, water is discharged to water tank, now record standard footage certificate; Repeat above-mentioned steps and successively water level is adjusted into 100.0cm, 150.0cm, 200.0cm, and after record standard footage certificate, start revesal calibrating;
Fetch boiling water on level controller " revesal water pump control knob " water level be arranged on to 150.5cm(advise that setting value is a little more than calibrating point value herein, because after water pump quits work, close revesal back-water valve (BWV) and have the individual mistiming), when instrument shows that water level reaches 150.5cm, water pump stops automatically, now close revesal back-water valve (BWV) and (otherwise detect water tank, continue draining at once, slow during relative pump working), it is enough just in time at 150.0cm observing detected liquid level gauge water level value, if low, use point driving switch to start water pump water adding, if can opening water tank revesal back-water valve (BWV), height continues draining, record now gauge data, repeat above-mentioned steps water level is adjusted into 100.0cm successively, 50.0cm, and gauge data have been recorded, finally change liquid level gauge and start new calibrating.
Can the short time in verification process occur detecting water tank and plexi-glass tubular level value inconsistent, this be mainly because detect water tank and plexi-glass tubular connecting tube thin, cause the liquid level can not Fast synchronization, need an equilibration time; In verification process, add water and discharge water too fastly, can adopt in two ways and to change, the one, pump speed control is slowed down, the 2nd, upper water and draining valve is half-open, reduce water amount; If the bright pump working that represents of positive and negative Stroke Control instrument point driving switch in verification process, because operating the problems such as discontinuous,, there is this situation in the situation that there will be positive revesal water pump all to work, as long as corresponding pump power is closed.
To sum up, the utility model accomplishes the end in view.
