Description
Technical field
The utility model belongs to fluid metering technical field, relates to a kind of temperature non-insertion multiparameter flowmeter.
Background technology
For obtaining fluid flow, temperature, pressure and other parameters in pipeline, need to arrange flowmeter in fluid management.Be conventionally used to the temperature sensor normally after coated metal overcoat measuring pipe network, directly in insertion flowtube, to obtain fluid temperature data, but, sensor will certainly cause interference to flowtube inner fluid flow state after inserting, and affects the accuracy that in pipe network, data on flows is measured.
Utility model content
In view of this, the utility model provides a kind of temperature non-insertion multiparameter flowmeter, and its temperature sensor can be inserted in flowtube can be detected, and avoids causing interference to flowtube inner fluid flow state.
Its technical scheme is as follows:
A kind of temperature non-insertion multiparameter flowmeter, comprise flowtube, described flowtube outer wall is provided with the sensor installation cavity caved inward, and this sensor installation cavity bottom surface is provided with the groove for mounting temperature sensor chip.
Adopt above structure, temperature sensor chip can directly be installed in the groove in this sensor installation cavity, temperature sensor chip and this groove form a temperature sensor, avoid because directly stretching in flowtube, disturb fluid flow state thus affect flowmeter metering accuracy.Secondly, because temperature sensor is arranged on outside flowtube, do not need to increase extra sealing, simplify the structure of flowtube, be conducive to reducing production cost.
Between described groove floor and inner wall of flow tube, spacing is preferably 2 ~ 3mm, on the basis of guaranteeing flowtube tube wall strength, the Temperature numerical that temperature sensor is obtained and flowtube inner fluid actual temperature more close.
For avoiding temperature sensor and respective lines to threaten from high temperature and corrosion, extend flowmeter serviceable life, improve its reliability, described flowtube is provided with radiating seat at sensor installation cavity, and is connected with gauge outfit by this radiating seat.
For convenience of the layout of connecting line between respective sensor and gauge outfit, described radiating seat has the wire guide of up/down perforation, and this wire guide is communicated with sensor installation cavity.
As preferably, described radiating seat outer wall is evenly distributed with radiating fin along wire guide length direction, to strengthen the radiating effect of radiating seat, improves flowmeter resistance to elevated temperatures.
Described flowtube outer wall is provided with the tracting pressuring hole with this flowtube inner space, this tracting pressuring hole is communicated with sensor installation cavity, the inherent corresponding tracting pressuring hole position of described sensor installation cavity is provided with pressure transducer mount pad, and this pressure transducer mount pad is fixed with pressure transducer.This structure can be convenient to the measurement of flowtube fluid pressure, and rationally distributed, compact conformation.
Beneficial effect:
Adopt the temperature non-insertion multiparameter flowmeter of above technical scheme, temperature sensor does not need to insert in flowtube to be measured, avoid the interference to tube fluid, measuring accuracy is higher, have structure simple, compact, production cost is low, high temperature resistant, long service life, the advantages such as good reliability.
