Abstract
The utility model relates to a target type flow meter for oil fields. The target type flow meter is composed of an outer shell 1, measurement targets 2, a transfer rod 3, sensors 4, a signal amplifier 5 and a display 6, wherein, the sensor 4 is arranged on a connecting plate 7 at the top end of the outer shell 1; the transfer rod 3 connected with the sensor 4 is extended into the outer shell 1. The utility model is characterized in that both ends of the transfer rod 3 are respectively connected with 4-6 sensors 4 and fixed circular piece type measurement targets 2. The target type flow meter solves the problem that the original flow meter has poor stabilization, a lower precision, easy damage of instruments, etc. The utility model has the advantages of long service life, large measuring range and difficult damage of instrument.
Description
The utility model relates to the used flowmeters in field such as high oil field water injection, wastewater treatment metering, belongs to target type meter.
Vane type, turbine, orifice-plate type or turbine, eddy currents are adopted mostly at the measuring instrument that is adopted aspect the industrial sewage metering in the oil field at present.And vane type, turbine type be because rotational parts rate of wear height, and poor stability easily causes precision on the low side, and cumulative errors are big, can not strict control water injection rate; Orifice-plate type or turbine, eddy currents are subjected to pipeline vibration effect, and be big to the measuring error of low flow velocity, low discharge; It is shorter to exist serviceable life, and measurement range is less, and the pressure loss is big, especially in water when impure and the high pressure water injection occasion problems such as instrument damage appear easily.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and the target type meter of life-span length, good stability is provided.
The purpose of this utility model can reach by the following technical programs: this flowmeter is made up of shell, measurement target, transmission bar, sensor, signal amplifier, display, sensor is placed on the web joint on shell top, the transmission bar that sensor connects extends in the shell, and the sensor that transmission bar two ends connect the 4-6 sheet respectively reaches fixedly garden chip measurement target.
The utility model has following advantage than above-mentioned prior art: owing to transmit fixedly garden chip measurement target of bar one end, saved rotational parts, do not had the problem of parts depreciation, stability and precision improve relatively, and error is little, can control water injection rate; Transmit the sensor that bar one end connects the 4-6 sheet in addition, make flow not be subjected to the influence of pipe vibration, to the measuring error minimizing of low flow velocity, low discharge, the life-span is long, and measurement range is big, and the pressure loss is little; In water when impure and the high pressure water injection occasion be not prone to the problem that instrument is damaged.
Accompanying drawing 1 is a structure cut-away view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this flowmeter is made up of shell 1, measurement target 2, transmission bar 3, sensor 4, signal amplifier 5, display 6, sensor 4 is placed on the web joint 7 on shell 1 top, sensor 4 connects amplifier 5 and display, and the transmission bar 3 that sensor 4 connects extends in the shell 1, transmits sensor 4 and the vertical fixing garden chip that bar 3 two ends connect 4 or 6 respectively and measures target 2.
During actual the use, the two ends of shell 1 adopt car coat type to be connected with pipeline, and preceding straight length is no less than 600mm, and back straight length is no less than 300mm.When the measurement target 2 in the measured medium circulation duct impact shell 1, measuring the corresponding momentum of target 2 surface generations, momentum is passed to sensor 4 by transmitting bar 3, and one of sensor 4 output and the proportional voltage signal of flow of measuring momentum that target 2 bears and fluid are to signal amplifier 5.Handle signal by display 6 demonstration measured flux through amplifier 5.
