Abstract
The utility model relates to a protector for a level meter. A cable 4 of a level meter is externally provided with a casing tube 3 and/or a flexible support bar 5 which is fixed with the cable 4; the support bar 5 is supported on a pool wall 9 by a bracket 7; the lengths of the casing tube and/or the support bar 5 are consistent with the length of the cable 4. The utility model has the advantages that the level meter and the cable are fixed, so that the swing of a sensor due to the impact of water flow can be prevented; the level meter can be guaranteed to be subjected to only the action of water pressure from bottom to top all the time under complex water conditions; the mismeasurement due to the water flow, impurity, etc. can be eliminated; an original level meter is not required to be improved. The utility model also has the advantages of less investment, simple installation, and accurate and stable measurement.
Description
The utility model relates to a kind of liquid level gauge that liquid levels is used of measuring, especially a kind of protective device of liquid level gauge.
At present, measure height of water level and generally adopt strain chip static pressure liquid level gauge, be to hang the static pressure type sensor down by a cable to add converter, measure static pressure and atmospheric pressure in the water by the sensing element in the sensor, then the variable quantity of measuring is converted to measuring-signal by prime amplifier, be delivered to peripheral measuring amplifier, thereby the standard signal of exporting a 4～20mA is done further processing, this liquid level gauge is because structural reason can only be surveyed the water of stationary state, if at eddy current, impurity, under the fluctuation complicated situation, can cause and detect inaccurate and malfunctioning even jumping pump because sensor vibrates with the current fluctuation with the interlocking of pump; Cause the flexible up and down of cable bending, sensor also can cause measuring error because foreign material in the pond such as iron oxide are piled up simultaneously, so this liquid level gauge measurement range is narrow.
The purpose of this utility model is the protective device that obtains a kind of liquid level gauge, can reduce liquid level gauge because the measuring error that operating mode badly causes enlarges its usable range.
For achieving the above object, the technical solution that the utility model proposes is:
A kind of protective device of liquid level gauge is the support bar 5 that sleeve pipe 3 is arranged and/or be fixed together with cable 4 outside the cable 4 of liquid level gauge.
The length of sleeve pipe 3 and/or support bar 5 is consistent with the length of cable 4.
Fig. 1 is the structural representation of the embodiment of the utility model liquid level gauge protective device.
Fig. 2 is another embodiment of the present utility model.
Below in conjunction with Figure of description and embodiment the utility model is done and to be described in further detail:
Referring to Fig. 1,1 is transmitter, and 2 is the process web member, and 4 is cable, is connected with sensor 8 under the cable.The utility model is at cable 4 outside mounting sleeves 3, and as adopting the galvanized iron conduit of diameter 80mm, sleeve pipe 3 is supported on the pool wall 9 by support 7, can fix whole liquid level gauge like this.Cable is fixed together by Plastic Bandage 6 and support bar 5; support bar 5 has certain flexibility; for example adopt the copper pipe of 5mm diameter; like this; can play the effect of carrying cable, because cable has 7,8 meters long, the length of support bar 5 is consistent with cable length; therefore support bar 5 has certain flexibility can be so that install, and present embodiment has the liquid level gauge protective device in the pond of confining bed above being.For the pond that does not have top cover above the pond, sleeve pipe 3 can be fixed on the pool wall 9, referring to Fig. 2, be that sleeve pipe 3 is welded in (11 are weld seam) on the steel plate 10, steel plate 10 is fixed on the pool wall 9 by swell fixture 12.
The utility model is owing to fix liquid level gauge and cable, can prevent the swing of the sensor that water impact causes, thereby guarantee that liquid level gauge remains the effect that only is subjected to water pressure from bottom to top under the regimen of complexity, it is inaccurate to eliminate the measurement that causes owing to current, impurity etc., this device needn't improve original liquid level gauge, investment seldom, and be applicable in pump pond, cesspool, water collecting basin or the large reservoir of all kinds of water treatment plants and install and use, be not subjected to the influence of installing space height, install simple, it is accurate, stable, practical to measure.
