Mud tank fluid level sensor

Jan. 14, 2011 - PRLog -- Mud tank fluid level sensor also called fluid level gauge, fluid level meter, content gauge, they are units which serve to monitor and control the level of operating fluid. GN solids control provide content gauge to measure the drilling mud level in the mud tank.

Types of Fluids level sensor

1 based upon mechanical measuring principles
Liquid level gauges of the type haying a buoyant float mounted on a pivoting float arm. Such pivoting float-type gauges typically utilize mechanical or electrical mechanisms that sense the angular position of the float arm with respect to a stationary support arm or other structure.
1)Magnetic and mechanical float  The principle behind magnetic, mechanical, cable, and other float level sensors involves the opening or closing of a mechanical switch, either through direct contact with the switch, or magnetic operation of a reed.
2)Pneumatic  Pneumatic level sensors are used where hazardous conditions exist, where there is no electric power or its use is restricted, and in applications involving heavy sludge or slurry.

3)Conductive  Conductive level sensors are ideal for the point level detection of a wide range of conductive liquids such as water, and is especially well suited for highly corrosive liquids such as caustic soda, hydrochloric acid, nitric acid, ferric chloride, and similar liquids.

2 based upon the well-known capacitance measurement principle.

Radar level gauges are in wide use for making non-contact measurements of the level of products such as process fluids and other materials. These devices utilize antennas to transmit electromagnetic waves toward the material being monitored and to receive electromagnetic waves which are reflected at the surface of the material being monitored.

Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high frequency (20 kHz to 200 kHz) acoustic waves that are reflected back to and detected by the emitting transducer.

Ultrasonic level sensors are also affected by the changing speed of sound due to moisture, temperature, and pressures. Correction factors can be applied to the level measurement to improve the accuracy of measurement.

By using a fluid level sensor , the fluid level can be easily seen on the outside of the tank. The fluid enters the unit via the lower connection bore and is clearly visible in the tube. Selection of the correct size allows the respective level of the fluid to be monitored.
