Quick Answer: Burkert 8025 Flow Meter Programming Essentials
Programming a Burkert 8025 flow meter or totalizer requires navigating the digital display menu with the four push buttons. You set the K-factor, choose engineering units, configure the pulse or 4-20 mA output, and lock the menu with a security code. Most field engineers finish the basic setup in under 10 minutes if the pipe data and sensor type are known in advance.
Getting into the Burkert 8025 Setup Menu
You press and hold the ENTER key for about 3 seconds to wake up the programming mode. The display shows CODE, and the factory default is 0000. If a custom code has been set and lost, you need to short two pins on the internal terminal block to reset it. We have walked several customers in Vietnam and the Philippines through this step by phone after they locked themselves out on a wastewater dosing line.
Once you are in the main menu, the first choice is usually the INP selection input type. You pick FLOW SENSOR if you have a paddle wheel, turbine, or oval gear meter with a pulse output connected to the 8025. For a 4-20 mA transmitter from a Coriolis or electromagnetic flow meter, you select ANALOG instead. This single decision routes you to completely different submenus.
Setting the K-Factor and Engineering Units
A pulse input device needs a K-factor. The Burkert 8025 accepts values from 0.060 to 99999 pulses per litre or gallon. You enter the exact number printed on the sensor nameplate. For a paddle wheel in a DN25 pipe measuring clean water, a typical K-factor is 49.85 pulses per litre. If you make a mistake here, every flow reading will be off by a factor, and the 4-20 mA output will carry the error straight into your PLC or SCADA.
After the K-factor, you choose the flow rate unit L/s, m3/h, GPM, or even barrels per day for oilfield applications. The totalizer unit follows separately. Many customers in the Middle East switch the flow rate to m3/h but keep the totalizer in imperial gallons because their reporting software expects that mix. The 8025 handles dual units without any extra hardware.
Configuring the 4-20 mA Output or Relay
The analog output needs a 4 mA and a 20 mA flow value. If your pump operates between 0.5 and 8.0 m3/h, you set 4 mA to 0.5 m3/h and 20 mA to 8.0 m3/h. The display then shows flow values and the loop current in parallel. You can also invert the signal 20-4 mA if your control system expects a fail-safe inverted loop.
Relays on the 8025 can act as pulse output, frequency output, or high/low alarm. When a food plant in Thailand wanted a relay to trip a warning light at 2.5 m3/h on a CIP return line, the configuration took three steps. Select RELAY 1, pick THRESHOLD, define the limit, and set a hysteresis of 0.2 m3/h so the light does not flicker at the exact trigger point.
Digital Display Options and Filtering
The 8025 LCD display can show flow rate, totalizer, or alternating both with a configurable toggle delay. In practice, a damping filter of 2 to 4 seconds smooths turbulent flow readings from vortex or paddle wheel sensors. Go too high, and you risk hiding real process changes. For fast batch operations, many engineers set the filter to 1 second and manage noise through sensor placement instead.
You can also lock the display with a user code from 0001 to 9999. After three wrong attempts, the unit locks for 5 minutes. This has caused genuine panic on a night shift in a dairy factory in Australia because nobody knew the code. We tell everyone to write the code on a label inside the panel door. That simple step saves a service call.

Last year a water treatment plant in Kenya installed an 8025 with a remote paddle wheel on a DN50 line. The display showed flow but the totalizer did not count. The engineer had set the totalizer unit to US gallons but the pulse output mode to 4-20 mA instead of TOT. One submenu change and the totalizer started recording volume. The 8025 separates flow and totalizer output assignments, and that detail catches a lot of first-time users.
Another common mistake is leaving the K-factor at the factory default of 1.000 pulses per litre. The display then shows a flow rate that looks plausible but is not real. Always cross-check the first reading with a clamp-on ultrasonic meter or a known process condition.
When You Need an Alternative to the Burkert 8025
The Burkert 8025 works well for clean fluids with low viscosity. But for high-viscosity fluids above 100 cP, like heavy fuel oil or glucose syrup, a paddle wheel sensor loses accuracy. In those applications, we suggest an oval gear flow meter with a direct pulse input to your display or PLC. For conductive liquids without particles, a mag meter with a built-in display avoids the K-factor guesswork completely.
If you are dealing with seawater, chemical dosing at 60°C, or need ATEX Zone 1 certification, the display electronics and the sensor must match the hazard. The Burkert 8025 with a remote sensor can meet many ATEX requirements, but the wiring and barrier selection matter more than the programming. We help customers in Indonesia and Nigeria specify the full loop sensor, display, barriers, and cable length because one missing detail delays commissioning for weeks.
Silver Instruments Support and Replacement Options
We stock paddle wheel flow meters, oval gear meters, electromagnetic flow meters, and 4-20 mA compatible displays that can replace a Burkert 8025 with the same panel cutout. If you need a display that mimics the 8025 menu structure so your operators do not need retraining, talk to us before you buy a replacement. We have retrofitted dozens of panels in Southeast Asian food factories exactly that way.

FAQ: Burkert 8025 Programming Quick Fixes
What to do if the display shows 9999 and freezes?
The totalizer has overflowed. Reset the totalizer in the TOT menu or set a higher totalizer unit like m3 instead of litres.
How to change from litres to m3?
Go to UNIT, choose FLOW RATE, scroll to m3/h. The totalizer unit changes separately under TOT UNIT.
Can I use the 8025 with a Coriolis meter?
Yes, if the Coriolis meter outputs a frequency or 4-20 mA signal. Select the matching input type INP and wire the signal to the correct terminals.
Why does the relay chatter at low flow?
The hysteresis value is too small. Increase the hysteresis to 0.5 % of the flow range or add a delay of 2 seconds in the relay settings.
What sensor types work with the 8025 without extra calibration?
Burkert paddle wheel sensors with yellow label, certain turbine meters, and oval gear meters with open collector NPN pulses. Always match the pulse type to the 8025 input terminal PNP, NPN, or Namur.
