Ultrasonic level meters ULM® is self contained device that includes electroacoustics transducer and electronic module. The
level meter ULM transmits series of ultrasonic pulses which propagates towards the liquid surface. Refl ected acoustic wave is
received back in the ULM transducer and processed in electronic module. The distance calculations are based on time of fl ight
of the acoustic wave to the level and back.

ultrasonic level meters are compact measurement devices including an electroacoustics converter, central processor
unit and display module. Using the electroacoustics converter, the level meters transmit the sequence of ultrasonic pulses
that spread towards the surface level. The converter recuperates refl ected acoustic waves that are subsequently processed in
the electronic module. The intelligent evaluation block fi lters out interfering signals, compares the cleaned received signal with
the false refl ection map (e.g. from mixers, ladders, reinforcement etc.) and selects a suitable refl ection (echo). Based on the
period during which the individual pulses spread towards the surface level and back and based on the measured temperature
in the tank, the instant distance to the surface level is calculated. According to the level height, the level meter output is set and
the measured value is displayed on the display.

We are offering tubular type indicator.
Tubular level gauge is the simplest form of level indication in process industry. It is simple and reliable device for direct reading in atmospheric or pressurized tank applications. It is mounted parallel, along the side of tank. As the process level fluctuates, the level in the transparent glass tube changes accordingly and gives local liquid indication.

We are offering pressure switches.
Pressure switches are designed from vacuum to pressure. The most important component for controlling pressure is the sensing element. Pressure sensors for both metallic and elastomer are suitable for most applications. Pressure sensorsare normally bellows, diaphragms and piston. This works on force balance principle. Media pressure on the sensing element contracts the force of the range spring (adjustable by the adjusting nut) which moves the piston shaft only a few thousandths of an inch to directly actuate the electrical snap action switching element.
