Ultrasonic Level Transmitter | RWLM

Ultrasonic Level Transmitter - Overview

This non-contact ultrasonic level transmitter ensures virtually maintenance-free measurement. The measurement is unaffected by media properties such as dc value or density and can be calibrated without filling or discharging. It is also self-cleaning due to its vibrating sensor diaphragm. The sensor pulses a signal in the direction of the product surface. The signal is then reflected back and received by the sensor which converts it into a reading of the level of the liquid or solid level. Applications include storage tanks, chutes, pools, wells, drains, metering boxes, granaries etc.

Ultrasonic Level Transmitter - Features
- Level Range: 4,6,8,10,12,15,20,30m
- Accuracy: 0.5%-1.0%
- Resolution: 3mm or 0.1%
- Display: LCD Display
- Analog Output: Two Wires 4-20mA/250Ω Load

Radar Continuous Level Measurement | GF2291

Radar Continuous Level Measurement - Overview

This Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. It operates based on the Time Domain Reflectometry principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse. The reflected signal is dependent on the dielectric constant of the material; the feasibility of the measurement is εr ≥ 1.9. The TDR technology is unaffected by the properties of the medium as well as that of the space above it. Measurement is also unaffected by the change in the physical properties of the materials such as temperature, pressure, and dielectric constant. It's reliability and precise measurements are useful in challenging conditions like agitated liquids, aggressive media, heavy chemical fumes, pressurized tanks or foam. Easy installation is ensured as you enter the basic tank parameters via the transmitters HMI or the GF Eview software and then the device configuration is completed. Secure and fast mounting of the devices is enabled by multiple options for process connection and coatings. Its superb durability is a result of high-performance coatings that protect the contacting probes in harsh conditions, ensuring even greater reliability.

Ultrasonic Level Transmitters | GF2260

Ultrasonic Level Transmitters | GF2260

This rugged, high-performance ultrasonic level measurement transmitter, has transducer and processing electronics and a display/ programming unit incorporated in one instrument. It uses established high-end pulse echo transducers, which provide narrow beam angles and reliable measurement ranges up to a distance of 15 meters. For small, stand-alone tanks the transmitter provides a simple 2-wire 4 to 20 mA output, with additional power relay contacts. It can be programmed using push buttons and has a large, graphic display. For large and/or multiple tank applications, versions with HART interface are recommended, communicating directly with a panel mount controller or PLC. The HART protocol can easily be used for programming these versions.

Radar Level Meter | QT902

Radar Level Meter - Overview

This high-performance, high-precision, high-reliability Radar Level Meter is low maintenance and has a long service life. Suitable for harsh environments including volatile gases, high temperatures, high pressures, steam, vacuums and dust. The Level Meter is hardly affected by corrosion and foam, and a dusty environment will not affect its effectiveness. It can continuously measure different material levels. The 26GHz high-frequency transmitting frequency and the small beam angle concentrate the energy and allow for a stronger anti-interference ability. This results in improved accuracy and reliability. The antenna is small, easy to install, and has a variety of sizes to choose from. The wavelength is shorter, which has a better effect on inclined solid surfaces. Good results can also be obtained for small tank measurements.

Radar Level Meter - Features
- Explosion-proof Grade: Exia IIC T6 Ga
- Measuring Range: 30 meters
- Frequency: 26 GHz
- Temperature: -60℃~ 150℃
- Measurement Precision: ±2mm

Water Level Transmitters | MPX

Water Level Transmitters - Overview
- Hydrostatic level measurements For small and large volumes. This is performed by applying the sensor directly to the water column load to be measured. This method is suited for dams, reservoirs and equalising basins from 0 to 275 m in height.
- Pneumatic level measurements For measurements using the bubbling method. The sensor, without having water contact, measures the counter-pressure generated by an air compressor. This is also suited for reservoirs, rivers, dams and equalising basins from 0 to 135 m in height.
- Level measurements with floaters A precise, extremely robust and maintenance-free level measurement can easily be set up using a floater connected to the rotary encoder via a chain and gear wheel
Type MPA, MPB & MPC - These Submersible Transmitter Probes hang in water on a special cable with integrated steel wire and air tube.

Type MPG and MPJ - These Pressure Transmitter Sensors are screwed into the wall of the pipe or container.

Water Level Transmitters - Features
