Mechanical flowmeters are a common and reliable solution for measuring the flow of liquids in pipelines. Unlike electronic sensors, this device uses the flow of fluid to drive internal mechanical components to rotate or move, and then converts this motion into flow readings. These readings can be displayed on a local dial or converted into an electrical signal output. Due to their good durability, ease of understanding, and usually lower cost, mechanical flowmeters have become a core measurement tool in many industrial fields. Working principle The core principle lies in the fact that flowing fluids drive the movement of internal mechanical components, and the speed of the movement is directly proportional to the flow rate. Common types include: Turbine flowmeter: The fluid drives the rotor blades to rotate, and the rotational speed reflects the flow rate. Piston or elliptical gear flowmeters: Fluid drives the gears or pistons, and each rotation corresponds to a fixed volume. They are suitable for high-precision measurement, including high-viscosity liquids. Impeller flowmeters: Fluid rotates a blade-equipped impeller. Product example: FM-120 series mechanical flowmeters The FM-120 series mechanical flowmeters are a typical representative of this technology, designed for occasions that require simple and durable solutions. This series is usually equipped with a clear and readable local display that can show cumulative flow and instantaneous flow, and can operate without external power supply, making it suitable for remote monitoring, basic process monitoring, or as an independent calibration device. Main advantage The selection of the FM-120 and other mechanical flow meters offers…

For outdoor work scenarios such as construction sites, farms, remote mining areas, or emergency rescue operations, how to safely and efficiently replenish fuel for equipment has always been a significant challenge. Traditional iron oil drums are heavy, prone to rust, and difficult to handle. Now, a solution specifically designed to address this problem – a mobile fuel tank made of high-strength HDPE material, equipped with wheels, oil pipes, and fueling guns – is gradually becoming the industry standard, transforming into a reliable “mobile gas station”. Unbreakable “Outer Shell”: The Superior Performance of HDPE Material The core advantage of this mobile fuel tank lies in the use of high-strength polyethylene (HDPE) material. This is not ordinary plastic; it is a specially formulated “industrial-grade” material. 1. Exceptional Durability: HDPE itself has extremely high impact resistance and wear resistance. This means that the fuel tank can effectively resist dents, cracks, or leaks during daily handling,  and even accidental collisions，and has a much longer service life than traditional metal oil drums. 2. Inherent corrosion resistance: Fuel, especially diesel, is corrosive to many materials. The HDPE material is inherently compatible with diesel and gasoline, and will not undergo rusting or chemical reactions. This ensures the purity of the fuel and eliminates the risk of damage to the precision engine due to rust contamination. 3. Critical UV stabilization treatment: Outdoor equipment is exposed to sunlight for long periods, and ordinary plastics will age and become brittle due to ultraviolet radiation. The “UV stabilization treatment” mentioned at the beginning…
