Introduction
The metal tube ratometer flowmeter is a kind of variable area flow quantity measuring instrument. It has such features as small volume, large detection range and convenient operation. It is especially suitable to measure flow quantity of media with small flow velocity and small flow quantity.Intelligentized metal tube rotameters have field indication type and intelligentized remote transmission type. So it provides the customers with very wide selection spaces. In addition, advanced 16 bits micro processor and high quality industrialized components are adopted in the instrument, which ensures excellent performances of the flowmeter in various kinds of application situations.

Application
Male Thread Digital Display Vertical Metal Tube Rotameter Applications
The metal tube rotameter adopts 304/316 stainless steel structure, which can be used to measure the flow of liquid, gas, and steam. It is especially suitable for flow measurement of low flow rate, micro flow range, high temperature, high pressure, corrosive, conductive or non-conductive medium. it widely used in petroleum 、chemical、 food 、water treatment and other industries.
Installation
Metal tube rotameter installation
Installed flowmeter should guarantee the entry ≥5DN straight pipe section, export straight pipe section not less than 250mm; if the medium containing ferromagnetic material, magnetic filter should be installed in front of the flowmeter. （see magnetic filter and straight pipe section diamension diagram ）
1.For flow meter installed，ensure the measuring pipe perpendicularity is better than 5 and should be equipped with bypass,easy to maintain and clean and does not affect production..
2.Monitoring and control system in the control valve，should be installed downstream of the flowmeter.For gas measurement，Should ensure the working pressure is not less than 5 times of pressure loss of the flowmeter, to make stable work of the flowmeter.
3.Before install the flowmeter，The pipe should be welding slag purging clean；When installation to remove locking component in the flow meter;when used after installation，Slowly open the control valve，Avoid shock damage flow meter
