Product Details

Product Description:

QX-LC seriesLubricating oil elliptical gear flowmeterIt is a precision instrument used to measure liquid flow rate. A direct reading cumulative instrument is a volumetric flowmeter that measures the total flow rate of liquid flowing through a pipeline. The elliptical gear flowmeter can be equipped with two counting mechanisms: mechanical display head and electronic display head. The display head has the functions of displaying cumulative flow rate, instantaneous flow rate, and zero return, which can achieve on-site display and remote control. For different measuring media (acid, alkali, organic liquid, oil, food, etc.), flow meters can be made of different materials (cast steel, stainless steel, and 316), suitable for flow measurement work in industrial sectors such as chemical, petroleum, pharmaceutical, power, metallurgy, and food. The flowmeter with messaging function can be matched with our company's flow integrator and other instruments for centralized detection, outputting standard signals for automatic control and data processing, and can be directly connected to a computer network.

Lubricating oil elliptical gear flowmeterProduct Features:
1. High measurement accuracy: 0.2 and 0.5 levels;
2. Simple, sturdy, and reliable in operation;
3. Especially suitable for measuring media with high viscosity, and insensitive to changes in the viscosity of the measured liquid;
4. Easy to install. There is no need for straight pipe sections before and after the flowmeter, even if the flowmeter is close to valves, bends, reducers, or expanders, there is no need to install straight pipe sections.
5. QX-LC series cast iron elliptical gear flowmeter is widely used for measuring various oil products and non corrosive liquid media of cast iron
6. QX-LC-e type cast steel elliptical gear flowmeter, used for measuring high-pressure and low corrosive media
7. QX-LC-b is widely used for measuring highly corrosive liquid media such as acids, bases, salts, and organic compounds
8. To prevent the gears of the flowmeter from getting stuck by impurities, a filter must be installed upstream of the flowmeter
9. Explosion proof grade: ExiaICT6
