The ultrasonic level detector/controller is an advanced electronic level sensor without moving parts. It is developed on our innovative technology and can provide real non-contact level measurement for closed container. It can test level height and produce low/high level alarm. The ultrasonic level can be installed at bottom of container to test level height,or installed at side vertical of container to judge whether there is liquid at monitoring points.

The level detector doesn't need to cut container or contact liquid directly. It is very easy to install and can make online installing. It can be used for high temperature/high pressure container. It can also supply precision level measurement for for poisonous substances,strong acid, strong alkali and various of pure liquids. The level sensor has no limit to fluid and container material.Thus, it can be widely used,e.g. to replace float switch. No matter whether the container material is metal or non-metal(e.g.plastic, glass,etc), our ultrasonic level controller can work well.

Typical Application

1.Industry tank with chemical liquid. 

Traditional level monitor way for chemical liquid is usually float switch. With float switch installing, it will require to cut hole. After installing, it also require to plug the hole. If the plugging is not good, it may be leakage and very dangerous. If use our ultrasonic level detector, it doesn't need to cut hole and installing is very simple. It will avoid risk of leakage.

2.Liquid status poisonous gas or flammable gas.

Such fluid are stored in closed tank. If cut it, it may be risk of leakage. Thus, it is better to select clamp on level measurement way.  

3.Traditional water level control.

Traditional way for water tank is float switch. It also requires to cut holes. The installing is very complicated and cost time and money. Also float switch is easily fault.Thus, it is ideal choice to select our ultrasonic level controller.

4. New project or innovative requirement.

Research is full of imaging. Maybe your new project requires clamp on level detecting. Our level will be suitable for your requirement with high cost-effective solution. 

Installing Way

1.If you want continuous level measurement, you may select bottom installing. This requires one piece of level sensor detector.

2.If you require high/low level controlling, you need side vertical installing. This requires two piece: one is for low level alarm, the other is for high level alarm.
