Product Q&A

Q:What type of liquids can this Oval Gear Flowmeter measure, and what is its maximum viscosity capacity?

The Oval Gear Flowmeter is specifically designed for measuring high-viscosity, non-abrasive liquids. It is ideal for applications involving heavy fuel oil, diesel, crude oil, lubricating oil, bitumen, syrups, resins, and various industrial chemicals. Standard models can handle fluid viscosities up to 2,000 mPa.s, while customized high-viscosity models are available for measuring fluids with viscosities up to 10,000 mPa.s.

Q:Does the Oval Gear Flowmeter require straight pipe runs before or after installation?

No, one of the main advantages of this positive displacement flowmeter is that it does not require upstream or downstream straight pipe sections. Because it operates on direct volumetric measurement driven by the meshing gears, its accuracy remains stable regardless of flow profile distortions or turbulent pipeline configurations.

Q:What housing materials, explosion-proof ratings, and signal outputs are available for industrial environments?

We offer body housing options in Cast Iron, Cast Steel, and Stainless Steel 304/316 to handle various corrosive and non-corrosive liquids. For hazardous petrochemical environments, the flowmeter is certified Exd II C T6 Gb explosion-proof. Output options include a standard mechanical totalizer, 4-20mA analog signal, pulse output, and RS485 (Modbus RTU) or HART digital communication.
