Operating Principles of Flow Switches ,Including Mechanical, Thermal Conductivity, Gas, Fire Protection, and Electronic Types.A flow switch is a device that monitors the flow rate of fluids (liquid or gas) and sends a switching signal when the flow rate reaches a preset value. It is widely used in industrial control, fire protection, water treatment, and…
The enterprise standard for explosion-proof flow switches mainly refers to their attributes produced as explosion-proof standards, which can pass the explosion-proof environment detection standards. Of course, its usage scenario will depend on the specific type of flow switch. For example, paddle flow switches are specifically designed for flow monitoring of water sources, water cycle heat…
What is an elliptical gear flowmeter Elliptical gear flowmeter is a precision instrument used to measure liquid flow rate. It is a direct reading cumulative instrument that measures the total flow rate of liquid flowing through the pipeline. The elliptical gear flowmeter can use two counting mechanisms: mechanical display head and electronic display head. The…
In hazardous industrial environments where flammable gases, vapors, or combustible dust are present, explosion-proof flow switches play a critical role in ensuring both personnel safety and equipment protection. These devices continuously monitor fluid flow and automatically trigger alarms or shutdowns when flow falls below a preset value, helping prevent pump dry-running, cooling system failures, and…
Liquid level instruments are widely used in industries such as water treatment, chemical processing, oil & gas, food and beverage, pharmaceuticals, and industrial automation. Reliable level measurement is essential for ensuring safe operations and stable process control. However, over time, factors such as electrical faults, environmental conditions, component aging, or improper installation can cause inaccurate…
