The magnetic flap level gauge is an on-site instrument that measures and controls liquid levels in tanks. It utilizes a magnetic float that rises with the liquid, causing a color-changing visual indicator to display the level. Beyond this visual display, the gauge can also provide 4-20mA remote signals, switch outputs, and digital level readouts. Designed for use in both open and closed pressure vessels, the gauge employs specialized high-temperature, high-pressure, and corrosion-resistant materials along with advanced manufacturing techniques to ensure suitability for a variety of applications. Additionally, customizable options like drain valves can be incorporated to meet specific on-site needs.

Introduction

Magnetic column (magnetic column) liquid level meter is based on the magnetic pole coupling principle, Archimedes (law of buoyancy) and other principles cleverly knot According to the characteristics of mechanical transmission, a special device for liquid level measurement is developed. On this basis, its use is continuously expanded range,extend a variety of types of products, in the detection of liquid level at the same time we give them more practical functions.

In order to expand its use range, can also increase the liquid level transmission device according to the relevant standards and requirements, to output a variety of telecom-munications number. Among them,4~ 20mA current signal is a more commonly used one. For example, the magnetic switch signal is available while the liquid level is being monitored. To control or alarm the liquid level; 4~20mA transmission sensor is added on the basis of the turning column level gauge, which can be monitored in the field. At the same time, the change of the liquid level is transmitted to the control room through transducers, cables and instruments to realize remote monitoring and control.

Installation

1. The magnetic level gauge shall be mounted vertically on either side (side mounted) or above (top mounted) of the container.

2. Confirm connection specifications, pressure range, and temperature limits.

3. The specific gravity of the medium must be greater than that of the floating ball on the nameplate of the liquid level gauge.

4. Liquid level gauge to avoid impurities and magnetic powder into, otherwise it will prevent the cylinder float free floating and magnetic field disorder, so that the liquid potential meter is invalid.

5. During installation, the magnetic switch should avoid violent impact, and the magnetic field interference should be avoided within 10cm around.

6. When the load of the magnetic switch is inductive or capacitive, a RC circuit is connected in parallel at both ends of the contact.

7. Please check whether the wiring and voltage are correct before transmission to avoid accidental damage to the transmitter or magnetic switch.

8. For the jacket type liquid level meter, the user should pay attention to the correct use of the jacket when using: first, the hot water through the jacket or the steam must be clean; Secondly, the jacket is designed to use the pressure of 2.5mpa, so it should be maximum when adding steam and hot water.The pressure should not exceed 2.5mpa; Third, in order to ensure the effective use of steam or hot water, it is recommended that the connection of the upper and lower drainage tubes should be the upper drainage tube is the inlet and the lower drainage tube is the outlet, and the connection is reliable to prevent steam or hot water overflow.

9. Prevent the drainage port from being blocked. Stop valve should be installed in front of instrument.

10. Do not open the vacuum stop valve with vacuum jacket.
