Elliptical gear flowmeterIt is a type of volumetric flowmeter used for precise continuous or intermittent measurement of liquid flow rate or instantaneous flow rate in pipelines. It uses mechanical measuring elements to continuously divide the fluid into individual known volume parts, and measures the total flow volume based on the number of times the measuring chamber sequentially and repeatedly fills and discharges that volume part of the fluid. Especially suitable for flow measurement of high viscosity media such as heavy oil and resin.
Precautions for use:
1. The pipeline should be cleaned before installation. If the liquid contains solid particles, a filter must be installed upstream of the pipeline; If it contains gas, an exhaust device should be installed.
If there is gas mixed in the measured liquid medium, it can also cause measurement errors.
3. The flow rate in the pipeline should not increase or decrease sharply, and phenomena such as pipeline vibration, hydraulic shock, and rapid pressure fluctuations should be avoided, otherwise it will affect the normal operation of the instrument.
When the flow rate exceeds the specified large flow rate, the wear of the elliptical gear increases with the increase of speed, and the pressure loss increases sharply. It should be avoided from use. Below low flow rates, although it can still be measured, the error increases. The starting flow rate of the flowmeter is about 2% of the large flow rate, and the normal working flow rate is preferably 70% to 80% of the large flow rate.
5. The temperature of the tested liquid should not exceed the specified value, otherwise the instrument will not work properly and may even get stuck. Changes in liquid temperature can also cause additional errors in viscosity.
Elliptical gear flowmeterIt has wide applications in industrial automation, fuel consumption monitoring, water treatment and supply systems, medical equipment, and other fields. Its high precision and reliability make it an ideal choice for ensuring stable and safe production processes.
