[0002] In a hydraulic system, an electromagnetic flowmeter is often used to monitor the flow rate of hydraulic oil to ensure the normal operation of a mechanical device. In addition, in addition to monitoring the flow rate, the electromagnetic flowmeter can also monitor the pressure in the hydraulic system. This measurement method is not only suitable for general conductive liquids, but also for strong corrosive liquids such as strong acids and strong bases, and liquids uniformly containing liquid-solid two-phase suspension.

[0003] However, the conventional electromagnetic flowmeter is directly installed, and the flowmeter is exposed to an industrial environment without a protection device for the electromagnetic flowmeter, which may adversely affect the performance of the flowmeter in a relatively harsh working environment and reduce the service life of the flowmeter. The present application provides a low-flow-rate hydraulic oil electromagnetic flowmeter which can protect the flowmeter. CONTENT OF THE INVENTION

[0006] By adopting the above technical scheme, hydraulic oil often appears in an industrial environment, and the environment is relatively harsh. In a harsh environment, the electromagnetic flowmeter is directly exposed to the harsh environment for work, which may cause equipment failure or measurement inaccuracy.

[0013] In a preferred embodiment, a connecting seat is movably arranged on the surface of the L-shaped fixing plate, and an electromagnetic flowmeter is fixedly arranged on the upper surface of the connecting seat.

[0014] By adopting the technical scheme, the connecting seat is a connecting component between the electromagnetic flowmeter (22) and the pipeline, which ensures that the sensor can remain stable during measurement and is not affected by pipeline vibration or other external factors.

[0015] In a preferred embodiment, a window is fixedly arranged on the surface of the L-shaped fixing plate.

[0018] By adopting the technical scheme, the first flange is connected with the outlet of the measured pipeline, and the second flange is connected with the inlet of the measured pipeline, so that the sealing and connection of the device and the measured pipeline are greatly improved.

[0019] In conclusion, due to the adoption of the technical scheme, the application has the following beneficial effects:

[0020] In the application, hydraulic oil often appears in an industrial environment, and the environment is relatively harsh. In the harsh environment, the electromagnetic flowmeter directly exposed to the harsh environment may cause equipment failure or measurement error. In the use process of the device, the protective shell can effectively protect the instrument from physical damage and corrosion, while maintaining the accuracy and beauty of the instrument, prolonging the service life of the electromagnetic flowmeter.

[0021] When the operator supplies direct current or alternating current to the electromagnetic flowmeter, the vertical push-pull plate can be pushed upwards to connect the direct current or alternating current power supply with the electromagnetic flowmeter. The protective shell does not hinder the power supply, and the installation is convenient without the need to disassemble the protective device. BRIEF DESCRIPTION OF DRAWINGS
