If the user needs to bring the display of the watch indoors, an integrated turbine flow meter can be used to direct the output signal through the cable to the flow totalizer installed in the room. The turbine flow meter can display the instantaneous flow and cumulative flow of biogas.
Gas Turbine Flowmeter When measuring the biogas installation flowmeter, if there is a valve near the upstream of the installation point, the valve will be continuously opened and closed, which will have a great impact on the service life of the sensor. It is very easy to cause permanent damage to the sensor and the sensor Avoid installation on very long pipelines that are overhead. After a long time, it is very easy to cause leakage of the seal between the sensor and the flange due to the sagging of the sensor. If it is necessary to install, the pipeline must be installed at the upstream and downstream 2D ​​of the sensor. Fasten the device.
Turbine flowmeter in a certain flow range vortex separation frequency is proportional to the average flow velocity in the pipeline, after the vortex generating body into the capacitive probe or piezoelectric probe (detector) and configure the corresponding circuit, which constitutes the capacitive detection turbine flow Meter or piezo-detection turbine flow sensor.
Gas Turbine Flowmeter To ensure complete functionality, the flow pattern at the inlet should be undisturbed. The length of the upstream straight section should be approximately 15 times the diameter of the turbine flowmeter (D), and the length of the downstream straight section should be approximately 5 times the flowmeter diameter (D). By placing a non-streamline vortex sounder in the fluid, two rows of regular vortices are generated alternately from both sides of the vortex, this vortex being called a Karman turbine.
Sand casting Production is one kind of old traditional metal casting process which could be date back to 4000 years ago in China.Because of easy making pattern and sand mold haveing lower cost,the sand casting process is also widely used in now days.The casting parts could be simple or complex shape and the material could be ferrous metal or none ferrous metal.
The advantages of sand casting:
1.Easy making pattern which could be wooden pattern or aluminum alloy material.
2.Easy making sand mould and removing.
3.Low cost in clay sand or resin sand which could be recyclable.
4.More short production process and leading time.
5.No limitation in product size and weight
6.No limitation in material grade.
