Radar Level Transmitter
The multilingual Quick Start Wizard guides you to program the transmitter using a few parameters, and has the SITRANS LR250 measuring in minutes. The transmitter can be programmed without opening the lid and consequently exposing the electronics to aggressive atmospheres via the intrinsically safe infrared handheld programmer or remotely via SIMATIC PDM using HART®. The new graphical local user interface (LUI) displays echo profiles and diagnostic information allowing the user to determine what is happening in the tank at a glance. The SITRANS LR250 includes self-diagnostic features that are communicated to the local display and across networks.
Siemens’ Process Intelligence signal processing evaluates dynamic echo signals. It applies algorithms (based on field data collected from over one million level measurement applications) to raw echoes to produce accurate and reliable level measurement readings. It can automatically ignore obstructions and is the processor behind the more advanced features such as diagnostic tools, Quick Start Wizard and Auto False-Echo Suppression. It also significantly improves the measurement accuracy in the low level of vessels containing low dielectric media. Process Intelligence makes the SITRANS LR250 the easiest to install and quickest to configure radar transmitter available today.
For remote tank level monitoring applications (vendor managed inventory) you can use the SITRANS LR250 with the IN4MA METRON gsm/gprs capable telemetry device. By knowing the level in a customers tank you can save money on logistics as well as improving levels of customer service.
As transportation costs go up then the savings provided by remote tank level monitoring go up and the benefits increase further still. In most situations the decision as to whether or not telemetry will pay for itself is not difficult, but it doesn't end there. Are you facing increased competition and reduced margins..? Does your sales team need that little bit extra to offer to the client in order to secure their business and if you could do that would you be able to tie the customer into a longer contract term…? In return your customer gets more efficient deliveries (they normally have to provide access etc..), as well as increased confidence knowing that they will never run out of product. Your customer becomes a mere bystander, you are reactive to situations that the telemetry is telling you about and everyone works better, sleeps better and saves money and the telemetry does all the hard work. You customer no longers has to get wrapped up to trek out to the tank and take a dip reading, risking life and limb balancing on top of a tank in a howling gale. You can even take it all one stage further and have automatic ordering…. It may be that the site where the tank is is unmanned so you save them a regular trip to site to take a level reading. The worse case is if your customer forgets to take a reading, runs out and their production stops - you get a call and it's panic stations. Your customer is losing money as production has stopped and you lose money as you've had to drop everything else and serve this one issue, setting a tanker off on a special journey that probably costs more than you make. Telemetry also gives you traceability. Jump on the internet, log on to the secure site and select the tank in question, enter a date range and hey presto - a graph showing the tank level. No more disputed deliveries, see if product is being drawn out of the tank when it shouldn't be to detect leaks and catch thieves. You can even give yourself a helping hand at stock take time.
