Corrosive liquids commonly found on work sites:

Strong acidic solutions such as sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, hydrofluoric acid, organic acids, mixed acids, etc;

Strong alkaline solutions such as sodium hydroxide, ammonium hydroxide, potassium hydroxide, barium hydroxide, etc;

Chloride (sodium chloride, magnesium chloride, calcium chloride, ammonium chloride, etc.), salt (sodium salt, potassium salt, ammonium salt, hypochlorite), oxidizing salt and other salt solutions.

Corrosive gases commonly found on working conditions:

Acidic gases such as chlorine, carbon dioxide, sulfur dioxide, nitrogen dioxide, nitrogen trioxide, hydrogen sulfide, hydrogen chloride, hydrogen iodide, hydrogen bromide, hydrogen fluoride, etc;Ammonia and other alkaline gasesbody

When measuring the flow rate of the corrosive liquids and gases mentioned above, it is necessary to choose a corrosion-resistant flowmeter. Below is a detailed introduction to the performance and advantages of various corrosion-resistant flowmeters for your reference and selection.

Flow meter priceDue to changes in selection specifications, caliber, and configuration, it is not a fixed price product,We need to select a quotation based on your working conditions.
