Model specification table

Intelligent metal tube float flowmeterConverter form

Intelligent metal tube float flowmeterAppearance and installation dimensions

The standard for jacket connection flange is GB/T9119 PN1.6 DN15
Intelligent metal tube float flowmeterInstallation form

The flowmeter shall be installed vertically, and the angle between the centerline of the flowmeter and the plumb line shall not exceed 5 °. An inlet straight pipe section of five times the nominal diameter shall be ensured upstream of the flowmeter, and a 250mm outlet straight pipe section shall be ensured downstream. If the medium contains solid impurities, a filter should be installed upstream of the flowmeter; If the medium contains ferromagnetic substances, a magnetic filter should be installed upstream of the flowmeter. For ease of maintenance and cleaning without affecting production, it is recommended to install a bypass pipeline. In order to avoid deformation of the flowmeter caused by the pipeline, the installation flange must be coaxial and parallel to the instrument, and appropriately support the pipeline to avoid pipeline vibration and reduce the axial load of the flowmeter. The control valve in the measurement system should be installed downstream of the flowmeter. When used for measuring gases, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float.

Intelligent metal tube float flowmeterattachment
We can provide users with accessories such as front and rear straight pipe sections, matching flanges, magnetic filters, gas damping devices, etc. If the medium contains ferromagnetic particles, a magnetic filter should be installed at the inlet of the flowmeter. The magnetic filter is equipped with magnetic rods arranged in a spiral manner to minimize pressure loss to the greatest extent possible. Each magnetic rod is wrapped in PTFE polytetrafluoroethylene to prevent corrosion of the medium.
The structure of the magnetic filter is shown in the figure:

Intelligent metal tube float flowmeterLimit switch alarm device
The limit switch alarm device in the indicator is composed of an induction head, aluminum sheet, etc. The induction head is installed at a position that can be cut by the aluminum sheet on the pointer shaft. By changing the position of the induction head, the limit value can be set arbitrarily. The induction head outputs a signal to the metal rotor flow indicator controller.
Technical Parameter
1. Power supply: 24V AC ± 10%
2. Power consumption: ≤ 3W
3. Working temperature: -25 ℃~60 ℃
4. Output contact capacity: 24VAC 3A
Wiring diagram

The change of alarm point requires opening the front cover, loosening the screw of the small pointer on the dial, adjusting it to the desired position, then tightening the screw, and finally installing the front cover.
Design, selection and ordering instructions for intelligent metal tube float flowmeter
1. According to whether the measured fluid is gas or liquid, use a gas or liquid metal tube float flowmeter correctly.
2. If the tested fluid is non corrosive, choose the ordinary type, and if it is corrosive, choose the corrosion-resistant type.
3. Please indicate the name, flow rate, pipe diameter, working pressure, temperature, density, viscosity, and other information of the tested medium when placing an order. Our company adjusts the scale according to the density and other requirements provided by the user, and produces a special flow scale.
4. Select appropriate specifications and varieties based on the measurement range and application scenarios of the fluid being tested. If there are special requirements for flow meters, please contact the company or contact the sales department via email.
