Liquid Level Probe

There are several reasons why an operator would install a liquid level probe, the most common is to determine the current level in a tank without incorporating any electrical equipment. Many companies either do not have access to electricity where the tanks are located or they simply do not want anything complicated. Other applications for a liquid level probe include but are not limited to sump level, drum level, and open tank level control. 

Most liquid level probes are inserted into the top of the tank through a threaded bulkhead fitting or flanged connection, this is the most common way to install a liquid level probe. Essentially a liquid level probe will either be used for continuous level measurement with a 4-20mA output that would be ran from the liquid level probe to a PLC or local LED display. Alternatively, a liquid level probe would be used from a high or low level switch. The liquid level probe would have a relay output and once the liquid level hits the liquid level probe it would switch and communicate to a local audible or visual alarm. The liquid level probe would alert the operator that their tank is in an upset condition, whether it is low or high level the liquid level probe can work in either application. It all depends on how the liquid level probe is connected to the alarm, normally open or normally closed are the standard options for a liquid level probe.   

The most common mistake that operators make when choosing a liquid level probe is that they will not take into consideration the wetted materials. Especially when they use one that should never really see the application, such as a high level liquid level probe. Many companies will make stainless steel liquid level probes and this will not be suitable in any aggressive chemical applications. It is highly recommended that the operator select the Level Pro CSS liquid level probe which is constructed of polyethylene material and suitable for most chemical applications. The simplistic is also a reason that operators lean towards the Level Pro CSS liquid level probe. Complete with a NEMA 4X junction box with an internal terminal strip so the operator can run his own cable into the switch to connect it to his alarm is very important to most companies. 

The Level Pro CSS liquid level probe is one of the only liquid level probes that have this as a standard feature. A market leading water treatment chemical skid manufacturer was looking for a corrosion resistant liquid level probe that would replace the floats that they were currently using, the issue was that the floats on the current liquid level probe would eventually stick and fail causing amisreading and a lot of overfills within the plant that purchased the units. The solution was to incorporate the Level Pro CSS liquid level probe, with no moving parts the capacitance liquid level probe would detect the high or low level and never become subject to failure due to sticking.
