Siemens Sitrans Flow Meter: Magnetic and Ultrasonic Calibration Manual
Quick Answer: You can calibrate Siemens Sitrans magnetic and ultrasonic flow meters using the official Siemens manual. The procedure covers dry calibration, wet calibration with a reference meter, and field verification. Silver Automation Instruments supplies the full PDF and can ship pre calibrated mag and ultrasonic meters from stock to Southeast Asia, Africa, and the Middle East.
This manual is what our engineers use when commissioning SITRANS FM MAG 5100 W, MAG 3100, MAG 6000 and the SITRANS FUS380 ultrasonic series. If you are an instrument tech in a desalination plant or a food factory, you know the moment a meter drifts by 0.5 percent your batch report becomes a problem. That is exactly why we keep the Siemens calibration steps ready and why we pre calibrate every meter before dispatch.
What the Siemens Manual Actually Says About Mag Meter Calibration
Here is the thing. Most engineers skip the zero check because the pipe looks full. But a half empty DN150 line will make a SITRANS MAG 5100 W output nonsense. The Siemens calibration manual forces you to do a zero point adjustment first. With the pipe full and liquid static, you trigger the zero function via the local display or HART communicator. The transmitter stores the zero offset, and you must see a value below 0.1 percent of the flow span. Silver Instruments always runs this step on a water rig before packing a DN50 or DN80 mag meter for a customer in Malaysia or Chile.
After zero, the manual walks you through the calibration factor trim. For a mag meter, the factory calibration factor is stored in the sensor memory and talks to the transmitter via the sensor chip. In the field you can perform a wet calibration using a master flowmeter or a weighing tank. You pass a known flow rate and adjust the K factor in parameter group 7 of the transmitter. The Siemens guide gives you the exact menu path and the password level. For a typical DN100 meter dosing sugar syrup at 80 kg/h in a beverage plant, the allowed deviation is plus minus 0.3 percent. Last year a dairy in Vietnam asked us for a re calibration procedure for three SITRANS MAG 3100 meters that had been in CIP service for 18 months. We sent them the Siemens manual section 8.4 plus our own quick guide and the issue was solved in a day.
Ultrasonic Flow Meter Calibration Using the Siemens Manual
Ultrasonic meters, especially the SITRANS FUS380 clamp on type, need a different mindset. The manual is clear about input parameters first. You must measure pipe wall thickness, outer diameter, liner material and fluid sound speed. A wrong entry of 1.5 mm on wall thickness on a DN200 steel pipe shifts the flow reading by almost 4 percent. We have seen this on customer sites many times. The Silver Instruments team in Nanjing always double checks these parameters with a PT100 temperature probe and a ultrasonic thickness gauge before calling the calibration done.
The Siemens calibration sequence for ultrasonic devices uses a transducer spacing verification and then a path calibration. On the FUS080 or FUS060 transmitter you access menu 3.2 and enter the reference flow. Many engineers stop there, but the manual also insists on a Reynolds number correction if you are metering heavy fuel oil at 180 cSt. That detail matters when a shipping company in Dubai measures bunker fuel at 400 m3 per hour. After field verification you lock the parameters with a service code and download the calibrati

When Dry Calibration Is Enough and When It Is Not
In practice, a Siemens magnetic meter ordered with a factory certificate can be dry calibrated on site within the first 6 months of operation. You simply check the electrode circuit, the coil resistance and the insulation, then compare the transmitter electronic output against a mA simulator. The manual has a pass/fail table for insulation values. For a MAG 3100 with PTFE liner in demin water service the insulation between electrode and coil should read higher than 20 megaohm. If not, do not even attempt a wet calibration; pull the meter and dry it.
But for ultrasonic clamp on meters, dry calibration is almost never enough. The acoustic coupling, the pipe condition and the flow profile vary too much. The Siemens manual clearly states that a wet calibration with a reference meter is mandatory for custody transfer applications. A gas plant in Oman used our engineer to perform a full wet calibration on two 8 inch SITRANS FUS380 units and we followed the manual step by step. The report showed 0.15 percent deviation before adjustment and 0.08 percent after. That is the kind of detail a buyer in Mexico or Nigeria will ask for when they send us a RFQ.
FAQ The 5 Questions Our Engineers Answer Every Week
How often should I calibrate a Siemens magnetic flow meter? The Siemens manual recommends every 12 months for meters in custody transfer or trade applications. For general process control every 24 months is typical. If you detect a shift beyond 0.5 percent, perform a field calibration immediately.
Can I calibrate a SITRANS FUS ultrasonic meter without the Siemens software? Yes, using the local keypad and the password you can access all calibration menus. But for full data logging and advanced diagnostics the Siemens SITRANS F US software is helpful. Silver Instruments can install and configure that software for you.
What parameters must I collect before wet calibration? You need the pipe ID, fluid conductivity, temperature, pressure, and the reference meter accuracy class. For ultrasonic meters add pipe material and sound velocity. Our support team asks for these exactly when you send your request to [email protected].
Does Silver Instruments supply the Siemens manual in Spanish or Portuguese? We can provide the English PDF and Siemens language packs. Our technical team in Nanjing can walk through the steps with your local engineer via WhatsApp at +86-25-52155837.
Can I get a pre calibrated meter that matches the Siemens manual exactly? Yes. Every Silver Instruments meter ships with a calibration certificate traceable to the Siemens factory procedure. Tell us your flow range, temperature, pipe size (DN), fluid name, and we will pre calibrate it on our 0.2 percent accuracy bench before air freight to your site.
