The flow meter OGM-R-25/40 series flow meters with mechanical totalizers are designed for accurate measurement of high viscosity diesel, kerosene, motor oil and other viscous liquids. The use of oval gears in meter readers ensures high measurement accuracy over a wide range of pumped product viscosities. The meter body of this flowmeter is made of aluminum and the oval rotor is made of steel. There is an analog counter and a 7-digit display on the mechanical recorder. Oval gear meter OGM-R-25/40 can be used both in stationary technical installations and in mobile vehicles for filling and pumping oil products.

Liquid flow meters with oval gears are designed to measure total and one-off quantities of light oil products, liquefied gas, and other non-corrosive liquids. The flow meter OGM-R-25 level gauge can be used both in stationary technical installations and in mobile vehicles for filling and pumping petroleum products. The design of the oval gear flow meter OGM-25/40 includes oval
