While do loop is used continuously monitor a condition, if the condition is fulfilled the statement insdie the loop is executed. Otherwise it will jump out of loop. In tutorial the while is continuously monitoring the Array J[i] which is having integer value, and displaying the largest value.

Material or product for detection is to be first considered. For Foam forming liquid we cannot use Standard Ultrasonic Level sensor, we have to specifically use Guided radar Sensor.
Guided Radar sensor consist of Probe and emit sound which would help for successful detection of liquid from foam. While Standard ultrasonic sensor only Sound for detection.
Standard ultrasonic sensor can be used for detection of water, sludge & High Viscous Materials.
3. Output:-
Usually ultrasonic level sensor comes with analog output
A. Analog Wired Output
B. Analog Wireless Output
A. Analog Wired Output -
0-10V DC and 4-20mA are mostly used in industries. 4-20mA are less prone to interference and can travel to more distance tan 0-10VDC
HART Wired output is a two way communication over 4-20mA. They can work in master slave mode with a distance of 1000m.
I/O Link protocol is a two communication which can travel lees than a distance of 20m.
B. Analog Wireless Output-
HART/IOT Wireless sensor work widely used. They both work as two way communication. Wireless sensor uses battery usully a life span of 5 to 10 years. As per requirement we can select life span. Frequency of Sensor depends upon country location. Different country have different Frequency band for wireless sensor. For USA, canada & Mexio it is aorunf 900MHz . For Europe it is arounf 868 mHz. 2.4 GHz is universal accepted frequency.
4. Process Temperature & Pressure:-
Process temperature is the temperature at which Sensor can work efficiently. Before selection of sensor manufacturer datasheet must be referred for operating Temperature.
Process pressure is the pressure at which Sensor can work efficiently. Usually standard sensor can work till 1 bar, but there are sensors that can work till 16bar also.
5. Range & Dead Zone:-
Range is the minimum and maximum Depth of tank, while selection from manufacturer datasheet this must be referred.
Dead Zone is the minimum distance between product and sensor, in which sensor can detect product effectively. Any product in dead Zone will not be detected by sensor. Mostly ultrasonic sensor have dead zone of around 100 to 200mm.
While designing Dead zone must be considered in addition to maximum level.
6. Enclosure :-
Enclosure type depends upon industry. For petrochemical industry enclosure is different and for pharma industry enclosure is different.
For hazardous industry different certifications line IECE, CSA & ATEX are used.
IP & NEMA rating is most widely used. IP rating is used in Asia and Europe region, while NEMA rating is widely used in USA.

This tutorial is About Learning how to use CASE Statement for Programming Tank Level Logic. CASE Statement are widely used as it helps for easy programming. Click Below for Video Tutorial:- Case statement Video Tutorial CASE Statements are also Called Switch Statement in C++. Case Statement acts as a switch. We can switch between Staements. Benefits of Using Case Statements :- 1. Better than Cascaded IF else statements. 2. easier to understand 3. Faster execution than IF Statements as CASE acts like a switch. Syntax:- Explanation:- 'Casename ' is similar to variable name ( user can define any name ) 'Statements' is also similar variable name (user can define any name ) Statements consist of Logic. we can switch between Different statements i.e switch between different logic. Statement 1 is Executed first when CASE is executed. In statement 1 user have to specify other statements to jump in form of Logic Please watch Youtube video below which would make understand bet
