1、 Overview

CS-LC-1805Oil specific flowmeterIt is a volumetric flowmeter that measures the total flow rate of liquid flowing through pipelines. This instrument has high measurement accuracy, is less affected by liquid viscosity, and does not require a straight pipe section to be installed in front of the meter. It is widely used for cumulative flow measurement of oils and high viscosity media in petroleum, chemical, pharmaceutical and health industries.It is a lightweight volumetric flow meter with pointer display, word wheel cumulative counting device and zero return device, widely used in liquid flow control in various industrial fields, suitable for various types of liquid measurement, using different manufacturing materials, and can meet the liquid flow measurement needs of various fields such as petroleum, chemical, pharmaceutical, food, etc

2、 Measurement principle:

Under the action of the pressure difference between the liquid at the inlet and outlet of the instrument measurement room, a pair of elliptical gears continuously rotate on the bearings and discharge the liquid. By measuring the number of revolutions of the elliptical gears, the total value of the liquid flowing through the instrument can be determined. If the volume Q discharged after one revolution of the elliptical gear and the number of rotations of the elliptical gear per unit time is N, then the volume of liquid flowing through during that time is NQ.

advantage:

The flowmeter installed correctly according to the requirements can ensure sufficient accuracy during use, and the accuracy of the cumulative value can usually reach 0.5 or 02 levels, which is a relatively accurate method. However, if the flow rate of the measured medium exceedsSmall, the impact of leakage errors will become prominent, and sufficient measurement accuracy cannot be guaranteed. Therefore, different model specifications have an allowable value for the minimum flow rate, and measurement accuracy can only be guaranteed when the actual measured flow rate is greater than the lower limit flow rate allowable value.When using, it is important to note that the temperature of the measured medium should not be too high, otherwise it will not only increase measurement errors, but also have the potential to cause gear jamming. For this purpose, use within the temperature range specified by the instrument.

After being installed correctly according to the requirements, sufficient accuracy can be ensured during use, and the accuracy of the cumulative value can usually reachLevel 0.2, Level 0.5It is a relatively accurate flow measurement instrument. However, if the flow rate of the measured medium exceeds

Small, the impact of instrument leakage errors will become prominent, and sufficient measurement accuracy cannot be guaranteed. Therefore, resin flow meters of different models and specifications have an allowable value for the minimum flow rate, and the measurement accuracy can only be guaranteed when the actual measured flow rate is greater than the lower limit flow rate allowable value.

Secondly, useOil flow meterIt is important to note that the temperature of the measured medium should not be too high, otherwise it will not only increase measurement errors, but also have the potential to cause gear jamming. Therefore, the elliptical gear flowmeter is used within the specified temperature range of the instrument.

After long-term use, the internal gears will be corroded and worn, which will affect the measurement accuracy. Therefore, it is important to observe regularly and dismantle for inspection. If conditions permit, it is best to calibrate regularly.
