Fork Level Switch to Measure Flowing Liquids in Vertical Pipelines

Product catalog summary

Introduction
This document discusses two innovative methods for using Fork Level Switches to measure flowing liquids in vertical pipelines, addressing common challenges in such applications.

Difficulties in Liquid Level Measurement

High liquid velocity and pressure in vertical pipes.
Intermittent liquid entry with bubbles and foams.
Limited installation space around pipelines.
High response requirement for level switches.

Method I
A lateral water storage tank is used with a welded water diversion plate to ensure water entry. A return tube allows water to return to the vertical pipe, maintaining consistent liquid levels between the tank and pipe.

Method II
A side pipe with a sensor flange and U-groove is used. The U-groove, designed to block liquid, allows the sensor to detect liquid level changes as liquid flows down the vertical pipe.

Advantages of Ring-11 Liquid Level Switch
The Ring-11 Liquid Level Switch is ideal for vertical pipeline conditions due to its high reliability and performance. It operates on the fork resonant principle, offering high sensitivity and the ability to measure low-density liquids. It is suitable for various liquids, including acids, alkalis, and liquefied gases, and performs well under challenging conditions like foaming or high viscosity environments. The switch is certified for safety and explosion protection, with multiple output options available.

Fork Level Switch to Measure Flowing Liquids in Vertical Pipelines-1

Fork Level Switch to Measure Flowing Liquids in Vertical Pipelines This article introduces a practical solution for the application of two innovative methods of Fork Level Switch for measuring flowing liquids in vertical pipelines. Difficulties in Liquid Level Measurement of Vertical Pipelines 1. Fast liquid velocity, high pressure in the vertical pipes, high impaction of the flow; 2. Liquid in vertical pipelines often enters intermittently, with many bubbles and foams; 3. Narrow space around the pipeline limits the installation position and the method of measuring sensor; 4. Requires high response of the level switch. A water storage tank is equipped laterally. To ensure the water enter into water storage tank, a welded water diversion plate is also equipped. A return tube is opened at the lower part of the water storage tank to facilitate the water return to vertical pipe. The diameter of the return tube is d, the size should be determined based on the size of water storage tank, so that when water 深圳计为自动

enters the water storage tank, it can quickly dip to the tines; when no water in the pipe, the water in water storage tank can quickly return to the vertical pipe, so that the liquid level of the water storage tank and the vertical pipe is basically the same. The vertical pipe leads out a side pipe with a matching flange of the sensor. The sensor is also equipped with U-groove as the sketch. The radius of U-groove is about 20 mm with thickness of 1 mm. It is cut by a round tube and welded on the flange of sensor. The total length of U-groove should be longer than the tines’ length. The length...

Fork Level Switch to Measure Flowing Liquids in Vertical Pipelines-3

Advantages of Ring-11 Liquid Level Switch On basis of the high requirements for liquid level measuring instruments to the working conditions of vertical pipeline, Ring-11 Liquid Level Switch is the ideal choice. Ring-11 Liquid Level Switch is a high reliability control switch specially used for liquid level measurements. The excellent, stable and reliable performance and quality are comparable to imported peers. Based on the fork resonant principle, when a fork vibrates in harmonic resonance comes in contact with measured liquid, its vibrating frequency will greatly decrease. The fork’s harmonic...
