Overview

Seojin gear level gauge SGL-1; SGL-2； SGL-3 Product Introduction: $r $nSGL Series SGL-1; SGL-2； The SGL-3 gear type liquid level transmitter utilizes the principle of balance between buoyancy and spring force of a float to measure the liquid level of liquids such as water, diesel, and marine fuel oil (heavy oil). When the float rises and falls with the liquid level, the gear mechanism connected to the float is driven by a spring and displays the liquid level value on the dial. At the same time, it can output a 4-20mA standard analog signal, achieving dual monitoring on site and remotely.

SeojinGear type liquid level gaugeSGL-1；SGL-2；SGL-3Product Introduction：

SGLseriesSGL-1；SGL-2；SGL-3The gear type liquid level transmitter utilizes the principle of balancing buoyancy and spring force of a float to measure the liquid level of liquids such as water, diesel, and marine fuel oil (heavy oil). When the float rises and falls with the liquid level, the gear mechanism connected to the float is driven by a spring to display the liquid level value on the dial, and can also output4-20mAStandard analog signal, achieving dual monitoring on-site and remotely.

SeojinGear type liquid level gaugeSGL-1；SGL-2；SGL-3Product Features：

•Support local disk display and remote control4-20mADual indication of signal transmission

•Compact structure, easy to transport and install on site

•Can be installed in situations with limited space and top clearance, suitable for storage tank top space restricted working conditions

SeojinGear type liquid level transmitterSGL-1；SGL-2；SGL-3working principle

When the storage tank is filled or drained, the float rises and falls with the liquid level until the total weight of the float and counterweight reaches equilibrium with the liquid buoyancy and spring force:

•Liquid level rise: buoyancy increases, spring is compressed, and the load borne by the counterweight decreases

•Liquid level decrease: buoyancy decreases, and the load borne by the counterweight increases

The gear mechanism connected to the float and counterweight directly displays liquid level changes on the dial; Simultaneously equipped with a built-in potentiometerR/I(Resistance)/Current converter, which converts liquid level changes into4~20mA DCStandard analog signal output, suitable for industrial control system acquisition.

fiveTheSeojinGear type liquid level transmitterPrecautions before installation

1. Applicable working condition limitations

◦Prohibited for: Temperature>85℃Storage tanks, high-pressure conditions, high viscosity media, and corrosive media

◦Recommended operating conditions: normal pressure-20~+60℃(Main body), non high viscosity, non corrosive liquid/oil

2. Anti turbulence measures

If there are turbulent disturbances such as stirring and liquid inlet impact in the liquid in the storage tank, a stabilizing cylinder must be installed/Buffer chamber to avoid measurement errors caused by fluctuations in the float.

3. installation space

Sufficient clearance should be reserved at the top of the equipment to ensure that the float can freely rise and fall with the liquid level without any risk of jamming.
