The metal rotor flowmeter is a type of variable area flowmeter. In a vertical conical tube that expands from bottom to top, the gravity of the circular cross-section float is supported by the liquid power, metal rotor flowmeter, metal tube float Flowmeters, Verabar flowmeter floats can rise and fall freely in the cone. It moves up and down under the action of flow velocity and buoyancy. After balancing with the weight of the float, it is transmitted through the magnetic coupling to the dial to indicate the flow. Generally divided into glass and metal rotor flowmeter. The metal rotor flowmeter is the most commonly used in the industry. For small diameter corrosive media, glass is usually used. Due to the inherent fragility of the glass material, the key control point also uses a rotameter made of precious metals such as full titanium. 1. High temperature resistant, up to 450°C Metal Rotameter, Metal Tube Floater, Verabar Flowmeter.
2. Suitable for measuring the flow rate of gas, liquid and steam with small diameter and low flow rate.
3. The magnetic coupling principle has no leakage and high pressure.
4. Affected by a certain viscosity, it is not suitable to measure high viscosity media.
5. When the flow rate exceeds 100m3/h, the pressure loss is large.
6. Intrinsically safe explosion-proof, explosion-proof type, suitable for dangerous occasions.
7. Mostly used for process control instruments, the best accuracy of 1%, generally 1.5%, a turndown ratio of 10:1.
8. The most suitable installation method is to enter the vertical installation.
9. Local pointer type, battery type, two-wire type, 220V AC power supply and other forms are available.
10. When measuring high temperature (lower than -30 °C) medium, it is best to use jacket type.
11. It is not suitable to measure media with large density changes.
12. Not suitable for measuring pulsation medium flow (eg metering pump outlet).
13. There is no temperature and pressure compensation for the gas meter and it needs to be considered separately.
14. For dense installation of multiple instruments or carbon steel process piping passing near the instrument, keep a distance of more than 100mm from the instrument to avoid magnetic interference.
15. When measuring the flux of a medium containing a large amount of ferromagnetic particles, a magnetic filter must be installed in front of the meter and purged regularly.
16. If you choose to use the instrument explosion-proof occasions, use round shell M4 indicator.
17. Metal tube float flowmeters do not require high straight pipe sections, generally 250mm after the first 5D.
18. Flowmeter high and low alarms are generally open-collector OC gates, which require external relays for current amplification. Relay output types are also available. The contact capacity is 1A@30VDC or 0.25A@250VAC.

Shackles are a versatile tool for connecting lifting slings, wire rope, chain, and rope - these links are essential for a number of rigging, lifting, pulling, and hoisting applications.
Because they come in a wide variety of styles and types, choosing the right one for the job can be confusing.
We've outlined some of the basics below. If you have any questions, contact one of our product specialists for more information.
