How to Correct the Scale of a Glass Rotary Flowmeter - Changzhou Chengfeng

Glass Rotameter is a kind of instantaneous flow measuring instrument which is easy to use, easy to read, and widely used. Selecting and using this instrument is extremely important. Regarding how the flowmeter sees the float reading, the following is an easy-to-use method for your reference:

The eyes are flush. Read the scale on the top plane of the rotor. Starting from the 0 scale, the data read on the rotameter is instantaneous flow. It is either volume flow or mass flow. If it is mass flow, you first convert to The volumetric flow rate can then be estimated by dividing the volumetric flow rate by the cross-sectional area based on the diameter of the rotameter.

The selection of glass rotor flow meter can be considered from the following aspects:

1. The object of measurement. That is, measuring the type of medium, pressure, chemical properties. Such as liquid medium, gas medium, corrosive media should be selected anti-corrosion flowmeter.

2. According to the price of choice. In general, the high accuracy and high price. According to the purpose of measurement, the instrument accuracy grade should be selected. For example, only the measurement medium throughput must be controlled. After trial operation adjustment, the throughput must be stabilized at a later time, then the accuracy is secondary.

3. The performance of the flowmeter itself, after the above conditions are determined, generally speaking, if the price does not change significantly, the needle valve can be preferentially placed on the upper part of the flowmeter; if there is a large flow hole, it is a direct flow rate scale; the structure is simple; Smaller outside size and so on. If it is a small flow range, ball floater type can be used, because it is stable when measuring, it is not easy to accumulate dust, has high precision and good interchangeability.

With the development of the instrumentation industry, the breakthrough in the technology of the instrumentation industry is inseparable from the support and efforts of the instrument manufacturers. Changzhou Chengfeng Flow Meter Company As a flow meter manufacturer, we strive to learn from others' new technologies, introduce advanced equipment, develop more technologies, and meet more customer needs. Chengfeng Flowmeter has also gradually sold its products abroad, and is widely favored by customers.

Anti Corrosive Pigment

Product Description


Silica Anti Corrosive Pigment, with white powder appearance, is mainly composed of calcium ion-exchanged amorphous silica gel. This new-developed Nanotechnology, without toxic and heavy metal, matches the environmental regulations. It can exchange calcium ions for the paint film and hydrogen ions on the substrate, to neutralize the acidic substances, maintain a high pH value, and prevent the substrate from erosive.

Meanwhile, the calcium ions can be combined with the metal oxide film to form a protective layer to protect the steel substrate, reduce corrosion, and prolong the service life. Ion exchange anti-corrosive pigments do not contain heavy metals, toxic, which provides a certain degree of rust protection.



Feature


1,Lower A/C pigment addition levels vs. existing IES pigments

2, Lower interaction with catalysts

3, Low sensivity to prolonged dispersion time.


Application Fields


Coil Coating, Appliance Finishes, Transportation and Heavy-Duty, Equipment Coatings, Metal Furniture Finishes.
