Elliptical gear flowmeterThe Oval Gear Flow Meter is a high-precision volumetric flowmeter primarily used to measure the volumetric flow rate of clean, non corrosive liquids such as oil, solvents, water, hydraulic oil, etc. The following is an explanation of the selection and installation precautions for elliptical gear flow meters.

Media compatibility: Confirm that the chemical properties of the liquid are compatible with the material of the flowmeter (housing, gears, seals).

Viscosity range: Provide the normal working viscosity of the liquid to ensure correct selection.

Temperature and pressure: Ensure that the rated temperature and pressure of the flowmeter meet the operating requirements.

Filter: A suitable mesh filter must be installed upstream of the flowmeter and regularly cleaned.

Avoid cavitation: Ensure sufficient inlet pressure (NPSH) to prevent liquid vaporization.

Correct flow direction: During installation, make sure that the fluid flow direction is consistent with the arrow direction on the flowmeter housing.

Reduce stress: Pipeline installation should avoid applying mechanical stress to the flowmeter body.

Signal output: Choose mechanical meter head, pulse output, 4-20mA analog output, or communication interface (such as RS485) as needed.
