The SI-3602 High Temperature Oval Gear Flow Meter is specifically designed for measuring the flow rate of high-temperature liquids, such as liquid coal tar, heated asphalt, and high-temperature heat transfer oil. The mechanical display can measure media at temperatures up to 200°C, while the intelligent digital display can measure media at temperatures up to 150°C. Temperature ranges from 280°C to 350°C can be customized.

To facilitate the normal transport and flow detection of media that easily solidify at room temperature, condense or crystallize at a certain temperature, within pipelines, it is often necessary to heat the media in the system pipeline to melt and maintain its temperature. However, since direct steam flow is not permitted at the installation location of the oval gear flow meter (to prevent damage to the flow meter), our company has designed an insulation jacket to be added to the outside of the flow meter housing.
Hot water, hot oil, or steam below 200℃ can be introduced into the insulation jacket to melt the solidified media inside the flow meter (or filter) and maintain a certain temperature, thereby ensuring the normal operation of the flow meter.
The filter installed before the oval gear flow meter can also be in the form of an insulation jacket; special orders are available upon request. The nominal pressure of the insulation jacket is 0.5MPa.
Industrial gear flow meters are designed for a variety of chemical applications. Suitable for viscous, non abrasive, clean liquids like: Water solutions, PetroleumOilChemicals, GreaseFuelsInk, Pastes.
Sino-Inst supports custom-designed high-temperature oval gear flow meters for users, based on different temperatures, media, pressures, and signal output requirements. For example, here are some parameters we previously customized for a client:
Oval gear flow meters, as a long-established liquid flow measurement device, offer a wide range of customization options. They are primarily used for flow measurement of high-temperature, high-viscosity, clean liquids.
Sino-Inst supports customization of high-temperature oval gear flow meters, including options such as cast iron and stainless steel. Mechanical or intelligent displays can also be configured to output signals. Please feel free to contact our sales engineers for custom high-temperature oval gear flow meter requests!
