Product Code: DT-LC Product Name: DT-LC oval gear flow meter Product Category: oval gear flow meter I. Overview oval gear flowmeter is a volumetric flowmeter for precise measurement of continuous or intermittent pipeline liquid flow or instantaneous flow. It is particularly suitable for flow measurement of heavy oil, polyvinyl alcohol, resins and other high viscosity media. Second, product characteristics 1, high measurement accuracy: 0.2 and 0.5; 2, mechanism is simple, rugged, reliable operation; 3, particularly suitable for measuring high viscosity media, but also by changes in liquid viscosity measurement insensitive; 4, easy to install. Without straight pipe before and after meter, even if the meter is close valves, elbows, reducers, expanding pipe, and without the installation of straight pipe. 5, DTLC-a type of cast iron oval gear meter is widely used in various oil and non-corrosive liquid cast iron metering medium 6, DTLC-e-type steel oval gear flow meter, for high-pressure, low-corrosive media measure 7, DTLC-b type widely used in strong corrosive liquid medium, such as acids, bases, salts and organic compounds measurement 8, in order to prevent the flowmeter gears are dead impurities card must be installed upstream of the meter filter 9, explosion-proof grade: ExiaIICT6 Third, the working principle consists of oval gear flow meter flow transmitter and counting mechanism. Installation of radiators, constitutes a high temperature between the transmitter and the flowmeter counting mechanism. Send change is made with a pair of oval gear rotor of the metering chamber and sealing couplings composed counter mechanism contains speed reduction mechanism, regulatory agencies, counters, sender.
