K-Tek has perfected a guided-wave radar level transmitter that measures the level of bulk solids and liquids under the harshest of conditions with an industry-leading accuracy of +/-5.1mm.
K-Tek has perfected a guided-wave radar level transmitter that measures the level of bulk solids and liquids under the harshest of conditions with an industry-leading accuracy of +/-5.1mm.
K-Tek's MT2000 overcomes the false echoes and complicated setup normally associated with conventional noncontact radar level transmitters while providing accurate height measurements even under the harshest conditions, wide variations in operating temperatures and pressures, and low dielectric constants.
The MT2000 also overcomes problems with product buildup and coating that cause most competitive devices to fail.
The MT2000 brings the benefits of radar level measurement to an expanded range of industries that seek an accurate solution to measuring the contents of tanks, silos, hoppers, bins, mixing basins, and sumps.
The MT2000 offers the traditional advantages of radar level measurement, such as measuring both liquids and solids, with no moving parts.
But the MT2000 goes one step further by employing a metallic probe to effectively act as a wave guide to direct the microwave pulses, eliminating the beam divergence common to conventional noncontact radar transmitters.
The MT2000 has no beam divergence, therefore, there are no false signals/echoes from objects other than the product surface, and there is no need to spend long hours programming the unit to ignore erroneous readings from the sides of the tank or other internal structures.
Setting up the MT2000 is easily accomplished via onboard pushbuttons - no laptop computer or special software is required.
The MT2000's probe can be cut to size, from 0.6-30.5m, in the field, and can operate even when bent in many applications.
The MT2000's microwave pulses do not reflect well off of low dielectric fluids.
However, by installing the MT2000 in a stilling well the energy is even more focused and low dielectric fluids like propane and butane are easy to measure.
K-Tek's coax-style probe is a waveguide installed in an integral 0.75in stilling well which is easy to install in low-dielectric fluids.
The MT2000 output is via 4-20mA, Hart, or Honeywell DE.
Results are locally indicated with a built-in scrolling LCD that offers measurements in a field-selected choice of feet, inches, millimetres, centimetres, metres, or even percent.
A linearisation table is included.
The MT2000 is immediately available for shipping to manufacturing and process engineers in plastics, petrochemical and power generation industries who wish to harness the advantages of radar transmitters to determine the level/height of materials in large containers and storage areas.
