How to choose a float meter
2011-8-6 9:54:01

Single-phase liquid or gas is the main measurement object of the float flow meter. Generally, liquid containing particulate solids or gas containing droplets are not suitable. The adherence of particles or tiny air bubbles in the float in the liquid flow will affect the measured value. For example, after the micro-flow meter is used for a certain period of time, an invisible adhesion layer will be attached to the float, so it will affect the percentage of the flow indication. .
If you are instructed on the spot, you should first consider the cheap glass tube float flowmeter . For example, if the temperature and pressure are not sufficient, you should choose a local indicating metal tube float flowmeter . The glass tube float flowmeter should be selected with a transparent protective cover. If the glass cone tube ruptures, it can block the fluid from being scattered in the forward direction, which is convenient for emergency treatment. Guide bars or ribbed instruments are suitable for gas, to prevent the float from breaking the cone tube due to careless operation. If the total accumulation or flow control needs to transmit signals remotely, generally a metal tube float flowmeter with an electrical signal output is selected. If the ambient atmosphere has explosion-proof requirements and there is an on-site gas source for control instruments, you should first consider using a gas remote transmission metal float meter. If you choose an electric remote transmission instrument, it must be explosion-proof.
It is more common to choose a metal tube float flowmeter when measuring opaque liquids, but a glass tube float flowmeter with ribbed tapered tubes is also possible. The position of the float is judged by the trace of the maximum diameter of the float contacting the ribs.
The jacketed metal tube float flowmeter is selected when measuring high-viscosity liquids with a temperature higher than the ambient temperature and liquids that are easy to precipitate crystals or solidify when cooled down.
