Gear Flow Meter Installation Considerations
In accordance with the requirements of the correct installation of the elliptical gear flow meter, when used to ensure adequate accuracy, the cumulative accuracy of the cumulative accuracy of up to 0.5, is a more accurate flow metering instrument. However, if the flow rate of the measured medium is too small, the instrument's leakage error will be prominent and sufficient measurement accuracy cannot be guaranteed. Therefore, the elliptic gear flowmeters of different model specifications have a permissible value for the minimum use flow rate. Only when the actual measured flow rate is greater than the lower limit flow allowable value, the measurement accuracy can be guaranteed. Second, the use of oval gear flowmeter should pay attention to the measured medium temperature can not be too high, otherwise it will not only increase the measurement error, but also make the gear stuck. For this reason, oval gear flowmeters are used within the specified operating temperature range of the instrument. After long-term use of the oval gear flowmeter, the internal gears will be corroded and worn, which will affect the measurement accuracy. Therefore, always pay attention to observations and remove them regularly for inspection.
Besides the commonly seen Overhead Crane and Gantry Crane , Weihua also provide specail cranes such as Jib Crane , Derrick Crane , Wind Turbine Maintenance Crane, deck cane, Roof Panel Making Truck Crane, Lift Platform , etc.
