Abstract
The utility model is the one-piece type electromagnetic flowmeters of temperature and pressure, this flowmeter comprises flange (1) and housing (2), in flange (1) welded case (2), in housing (2), Wedge shape pore plate is installed, it is characterized in that: upstream and downstream welding pressure probe outer tube (6) being respectively positioned at Wedge shape pore plate on housing (2), in pressure probe outer tube (6), fix upstream pressure probe (4) and downstream pressure probe (5) through nut lock.The utility model structure is simple, installs easily, easy to operate, avoids the shortcoming that the measuring accuracy of differential pressure transmitter is in the past not accurate enough, makes to measure more precisely reliable, can also provide temperature and pressure compensation simultaneously, make it more convenient.
Description
Technical field
The utility model relates to flowmeter, is specifically related to the one-piece type electromagnetic flowmeter of temperature and pressure.
Background technology
Wedge flow meter is a kind of differential pressure type flow instrument, liquid or the thick liquid of suspended particle pass through smoothly, viscous flow can not be produced, adhere to, precipitate at throttling element upstream side, the flow measurement of particularly suitable high viscosity, high concentration, crystallization mixture, dirty liquid and high dusty gas, be therefore widely used in oil, chemical industry, rock gas, control gold, iron and steel, electric power, water conservancy, plumbing, papermaking, pharmacy, brewage, the metering of the industry such as textile printing and dyeing and process monitoring.
When the fluid being full of pipeline flows through Wedge shape pore plate, the differential pressure of fluid is measured at Wedge shape pore plate upstream side and downstream, differential pressure signal is converted to 4 ~ 20mA current signal and exports by differential pressure transmitter, and this signal, after the process of artificial intelligence flow arithmetical unit, obtains flow value.But in actual applications, a lot of place, the measuring accuracy of this flowmeter can because the difference of environment and error to some extent, all two flanged d p cell transmitter and capacitance differential pressure cell in the past, its shortcoming makes measuring accuracy not high enough in a lot of situation, range is narrow, assembles more loaded down with trivial details, in-site installation inconvenience.
Summary of the invention
The purpose of this utility model is: provide a kind of temperature and pressure one-piece type electromagnetic flowmeter, avoids the shortcoming that the measuring accuracy of differential pressure transmitter is in the past not accurate enough, makes to measure more precisely reliable, temperature and pressure can also be provided to compensate simultaneously, more convenient.
Technical solution of the present utility model is: this flowmeter comprises flange and housing, on flange welding housing, in housing, Wedge shape pore plate is installed, it is characterized in that: the upstream and downstream welding pressure probe outer tube being respectively positioned at Wedge shape pore plate on housing, in pressure probe outer tube, fix upstream pressure probe and downstream pressure probe through nut lock.
Wherein, housing is positioned at the upstream welding temperature probe outer tube of Wedge shape pore plate, pops one's head in through nut lock fixed temperature in temp probe outer tube.
The beneficial effects of the utility model are: 1, flowmeter is when measuring, and the pressure probe of upstream and downstream measures the pressure at two respectively, are input to micro computer and obtain flow, improve accuracy of measurement; 2, carry out temperature survey, temp probe plays the effect of temperature compensation simultaneously, and upstream pressure probe also plays pressure compensated effect; 3, simplification is installed, more convenient to operate, prevented in the past because measurement environment badly causes the damage phenomenon of pressure pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 flange, 2 housings, 3 temp probes, 4 upstream pressure probes, 5 downstream pressure probes, 6 pressure probe outer tubes.
Embodiment
