During long-term operation, faults of flow switches are mostly related to installation deviation, medium contamination, parameter drift, or component aging. The fault manifestations and troubleshooting methods vary slightly among different types of flow switches. Below are general common faults and corresponding classified troubleshooting measures. I. General Common Faults and Troubleshooting Methods Fault Phenomenon…
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…
The instructions for explosion-proof flow switches roughly include the most common principles, application scenarios, and so on. Introduction to the principle of explosion-proof flow switch (taking electronic explosion-proof flow switch as an example): The principle is mainly based on the thermal principle, which includes two resistors inside a closed probe, one of which is heated…
Nine methods for repairing liquid level instruments 1. The direct sensory method is a method of using the direct sensations of the eyes, ears, nose, and hands to stop making judgments. It is a helpful wrist for testing the lack of sensation. All departments, levels, routes, and points can be jointly applied in the process…
