Mass flow meter purchase tips - focus on microfluidic control technology

Mass flow meters are a very common part of our life. At present, the valves commonly used in ordinary households are generally made of iron or copper. Because of the good mechanical properties of copper alloy, it has the advantages of less rust and strong corrosion resistance. The flowmeter is used for flow control. Since the flowmeter is easier to open and close than the gate valve, most of the current connection between the pipeline and the water meter is flowmeter. So what is the skill of buying it?
Quality flow meter purchase tips:
1 When measuring the flowmeter, the surface should be free of blisters. The surface of the plating should be evenly glossy. Pay attention to the defects such as peeling, cracking, charring, exposed bottom, peeling off, dark spots and obvious pitting. The surface of the sprayed surface should be fine. It is smooth and even, and there must be no defects such as sag and exposed bottom. The above defects will directly affect the service life of the valve.
2 The pipe thread of the flowmeter is connected with the pipeline. When purchasing, visually check the thread surface for obvious defects such as dents and broken teeth. It is important to pay attention to the effective length of the screwing of the pipe thread and the connecting piece, which will affect the reliability of the seal. Sex, pay attention to the effective length of the pipe thread when purchasing. Generally, the effective length of the cylindrical pipe thread of DN15 is about 10mm.
3 Flowmeters are generally marked with nominal pressure on their valve body or handle. When purchasing, they can be selected according to their own needs. To replace the current one, it is necessary to clarify the length of the structure so as not to be installed after purchase.
5 The pipe thread of the flowmeter has two kinds of internal thread and external thread, which should be purchased according to the needs; it should also be noted that there are some triangular valves made of zinc alloy on the market, and the flowmeter is sold at a lower price than the general product, but Corrosive and causing breakage.
Other than that. When choosing a mass flow meter, we should try our best to buy it in a regular building materials store or supermarket, so that the quality of the product and the after-sales service can be guaranteed. Because different ball valves have different uses and applications, we should choose different types of household valves according to different requirements of users.
