The NNR220A is a versatile, solid-state, Level Controller which has become increasingly popular for level measurement in chemical and petrochemical plants, power plants and food processing installations. It is normally part of a system controlling the liquid level in tanks, by monitoring its depth relative to a datum plane.

The basic principle of operation of the NNR220A controller is to measure the level of a liquid in a tank by measuring the acoustic echo from an ultrasonic transducer. The level inside the tank is determined either by direct indication from the transducer, or by calculating the difference between the direct level reading and a reference level. The ultrasonic signal is emitted from the transducer at a specific frequency and the time it takes for the sound to travel through the liquid and return is measured. By knowing the speed of sound in the liquid, the distance of the echo can be determined.

The NNR220A level controller can measure level accurately and reliably over a wide range of operating conditions and in a variety of liquids. The output of the controller can be used for direct control of a pump, valves, alarms or other associated equipment, while the controller can operate in either open or closed form. The controller also has the ability to detect a wide range of frequencies, so it can be used in systems with different types of liquids, such as water, oil, chemicals, and other fluids.

The NNR220A Level Controller is well suited for industrial level measurement applications. The controller is relatively easy to install and can be configured for simple point measurement or for continuous level measurement, depending on the application. It is also reliable and durable, so it can be used over a long period of time without any maintenance or worry.

The NNR220A Level Controller can be used in a wide variety of applications. It can be used for monitoring temperatures, flow, liquids, and even gas levels, and many other applications. It is used in chemical plants, petroleum refineries, and even food processing plants, just to name a few. The controller is also relatively affordable and cost-effective, so it is ideal for the budget-minded customer.

In conclusion, the NNR220A is a reliable and versatile level controller which is ideal for a wide range of level measurement applications. It is easy to install and can be used over a long period of time without maintenance. The controller can be used for monitoring a wide range of fluids, temperatures, and gas levels, and it is also extremely affordable for the budget-minded customer. The NNR220A is an excellent choice for monitoring the level of fluids in industrial applications.
