Selection of a water level gauge

Using float balls or magnetic flap switches to measure wastewater works fine; the problem might lie with the level gauge itself – for example, the selection of the density suitable for the float ball and the wastewater, jamming in the switching mechanism, or poor contact. It is necessary to conduct a thorough inspection. Contactless radar and ultrasonic waves can also be used, but care must be taken regarding water vapor caused by temperature.

For my brother’s level gauge, the sensor diaphragm is not in contact with the liquid. . . I guarantee 3 to 8 years of trouble-free, maintenance-free operation. Those who have used Haiyou all praised Brother; there are posts as proof: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1844429&extra=&page=1. .

A tuning fork switch will do; it’s not expensive either； Ultrasonic sensors are often used to measure the continuous liquid level in wastewater.

Durability and no false alarms – that’s the real key. https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1844429&extra=&page=1 .

Testing various types of wastewater for corrosion and scaling, testing desulfurization lime slurry, testing mud and pulp, as well as testing the cement slurry used by construction teams for building bricks and structures! You can all come to bro. My brother also likes to work on leftover problems, especially those measurement challenges that are difficult for him to solve – he’s particularly interested in them. . . . . . .

Basically, any level gauge that can measure water levels will work; a magnetic flip plate combined with a reed switch is a simple and effective solution

The medium to be measured is wastewater from production processes. Currently, a float level gauge is being used, but its performance is not satisfactory; sometimes the wastewater overflows yet the gauge does not send any signals. I am looking for a cost-effective level gauge that does not require frequent adjustments. There are many types of wastewater produced: those with deposits, viscous substances, foam, acidic or alkaline properties, as well as wastewater with small fluctuations in level, varying temperatures, and volatile substances – all of these factors affect the choice of level gauge. The current float level gauge does not work well; it fails to detect overflows in some cases. Rod-type float switches have also been considered, but issues arise due to the presence of deposits in the wastewater. 1: Float jamming; 2: Problems with the quality of the reed switch. With cable float switches, it seems that there are more problems with reed switches, as well as issues related to the sealing and flipping of the float itself. In short: there are many types of level gauges available, and it is most important to identify the operating conditions and select the appropriate one. . Some personal thoughts, to discuss together.
