Description
Technical field
The utility model belongs to a kind of flowmeter, is specifically related to a kind of electromagnetic flowmeter.
Background technology
Electromagnetic flowmeter is that a kind of metering of measuring conducting medium volumetric flow rate is only shown, and it is mainly made up of parts such as electromagnetic flow transducer, flow conversion and processing instrument.Have without throttle block stream unit, be difficult for stopping up, good corrosion resistance, Applicable media scope is wide, measuring accuracy is not subject to the impact of the physical parameters such as measured medium temperature, viscosity, density, pressure, proportion, its indicating value in certain conductivity range with the feature such as the class of liquids of being demarcated is irrelevant.Electromagnetic flowmeter is except measuring the flow of general liquid, also can measure the volumetric flow rate of liquid-solid two-phase liquid, high viscosity liquid and salt, strong acid, highly basic liquid, the industrial technology department such as can be widely used in cement, chemical industry, light textile, metallurgy, mine, papermaking, medicine, plumbing, food and drink, refine sugar, brewage, particularly at field of Environment Protection.At present, electromagnetic flowmeter oneself become the effective tool of quantitative management enterprise of environmental administration sewage discharge.
General electromagnetic flowmeter is in non-full pipe liquid flow measurement, exist following problems: in the time flowing through the liquid level of pipeline and be not full of whole pipeline, the cross-sectional area of fluid is not equal to the cross-sectional area of pipeline, in non-full pipe, the height of liquid level may change at any time, now the cross-sectional area formula of liquid medium is Protean, and likely have at any time larger fluctuation, this all can cause general electromagnetic flowmeter survey inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of electromagnetic flowmeter, can measure accurately non-full pipe fluid flow.
For achieving the above object, technical solution adopted in the utility model is:
This flowmeter comprises housing, is provided with measuring tube in housing, is provided with lining in measuring tube, and measuring tube interior conduit xsect is provided with liquid level gauge; Measuring tube is socketed with magnetizing coil, magnetizing coil connecting electrode, and magnetizing coil is socketed iron core outward; Housing is also provided with Switching Power Supply, and the two ends of housing are equipped with mounting flange; Housing is circumscribed with display control unit, and display control unit is provided with display screen and converter.
Preferably, Switching Power Supply is ultralow EMI Switching Power Supply.
Preferably, converter electron device used is SMD device.
Preferably, display screen is high definition backlight LCD display screen.
The beneficial effect that this electromagnetic flowmeter produces is:
1, be provided with liquid level gauge at measuring tube interior conduit xsect, measure the liquid level of liquid medium, the actual cross sections so just can obtain liquid medium and flow through flowmeter time, and then record the actual flow value that flows through flowmeter;
2, Switching Power Supply is ultralow EMI Switching Power Supply, is suitable for mains voltage variations scope large, and anti-EMI performance is good;
3, converter electron device used is SMD device, and converter volume is little, lightweight, and reliability is high, vibration resistance is strong, and welding point defect rate is low;
4, display screen is high definition backlight LCD display screen, saves the energy, convenient observation.
