The new Micropilot FMR6xB family
Featuring innovative 80 GHz technology, and developed according to the international functional safety directive IEC 61508, the new Micropilot FMR60B, FMR62B and FMR67B generation of devices rounds out the Endress+Hauser radar instrument portfolio.
The expert for measuring bulk solids is the Micropilot FMR67B. Whether in large tanks, tall silos, in dust and dirt, gas layers or deafening noise, the non-contact radar technology meets the highest international safety standards and the quality demanded by customers either producing solid end product or using bulk solid raw materials. An antenna featuring integrated compressed-air cleaning ensures that the instrument always provides reliable and accurate measurement, even in dusty environments.
Accuracy in tight spaces That makes the instrument so valuable for use in the tall silos commonly used to store bulk solids is the significantly smaller 3-degree radar emission angle. This makes it possible to measure in extremely tight spaces and also eliminates potential interference from existing fixtures. The instrument is also extremely easy to install and operates to an accuracy of 3 millimetres on solids even at extended distances (up to 125 metres).
Cutting-edge technology Another genuinely unique feature of this instrument is Heartbeat technology, which encompasses process and device diagnostics that guarantee safe plant operation with extended proof test cycles. Simple clear messages are given in the event of an issue arising and remedial actions are suggested by the device.
Heartbeat Verification verifies the correct function of the measuring device and generates a report without process interruption. This can be used to meet the requirements of QA procedures or standards and gives you confidence in the accuracy of the level measurement.
Heartbeat Monitoring offers additional parameters for predictive maintenance and/or process optimisation. Two setup wizards for foam or antenna build-up detection give the option of monitoring conditions in the vessel and taking timely corrective action. The benefits are increased process uptime and confidence in measured values.
80 GHz right for your application? Micropilot FMR60B is used for continuous non-contact level measurement of liquids, pastes and slurries. The measurement is not affected by changing media, temperature changes, gas blankets or vapours.
For applications in aggressive liquids, Micropilot FMR62B offers extraordinary advantages with its completely PTFE-filled and flush-mounted antenna, which allows very small process connections.
The perfect frequency
Heartbeat Diagnostics Competition between manufacturers of radar-based level measurement instrumentation has led to constantly higher radar frequencies. But does higher always equal better? Endress+Hauser’s level product manager Anwar Nawaz answers our questions.
What is the meaning of frequency when it comes to radar level measurement? The frequency influences the wavelength of the measuring signal. The higher the frequency, the shorter the distance between two waves. With a higher frequency the beam angle can be much smaller.
A narrow beam of only three degrees allows the Micropilot to measure down into a conical bottom silo or into tall narrow tanks with obstacles inside like struts or ladders.
So the higher the frequency, the better the measurement? No, because there are some disadvantages. A high-frequency signal loses strength when crossing through a medium. In practice this results in having more trouble with dust, foam or vapour. But also turbulent surfaces on liquids can be a problem. The signal tends to get scattered if the signal wavelength is smaller than the surface wavelength. In this case, it’s better to use a low-frequency signal.
So, what is the ideal frequency? There isn’t one. It all depends on the application. That’s why our portfolio encompasses measuring devices operating at different frequencies, using many software and hardware options. It’s only by talking to our customers and understanding their needs that we can provide them with the ideal solution. Our dedicated application consultants and industry managers use their extensive industry experience to get the right fit every time.
