Siemens Flow Meter Mag 8000: Battery Powered IoT Utility Main Probes
Quick Answer
The Siemens Mag 8000 is a battery powered electromagnetic flow meter for water mains and district metered areas. For utility main probes, the standard range is DN25 to DN300 with PN16 or PN40 flanges, an EPDM liner, Hastelloy C electrodes, and an IP68 housing. Silver Automation Instruments supplies a compatible battery powered electromagnetic meter with 4G, NB-IoT, or LoRa data logging.

What the Siemens Mag 8000 Actually Does on a Utility Main
The Mag 8000 is not an insertion probe. It is a full bore electromagnetic flow meter that installs between flanges on a water main. The term main probe often means a sensor or flow element on a distribution main. In this case the complete meter sits in the main line and measures flow using electrodes in contact with the water.
Utilities choose this meter because the battery inside runs the converter and transmitter. In remote areas of Vietnam, the Philippines, and Western Australia there is often no mains power at the meter pit. That is the core reason battery powered main probes are used.
Key Specifications for Utility Main Probes
Battery powered electromagnetic meters need water conductivity above 20 µS/cm. Potable water is usually 50 to 800 µS/cm. Raw water and groundwater normally exceed 100 µS/cm. If your water is below 20 µS/cm, a battery powered ultrasonic meter is a better fit.
The standard range is DN25 to DN300. Some projects push this to DN400. For DN350 and above, check the flange pressure rating and battery life. The typical pressure rating is PN16. PN40 flanges are common for higher pressure distribution mains. The liner is EPDM and the electrodes are Hastelloy C. Accuracy is usually 0.4 percent of rate. The housing is IP68 and can survive pit flooding.
Battery Life and IoT Data Logging
Battery life depends on the logging interval and the modem wake time. A 15 minute logging interval can deliver 8 to 10 years. A 1 minute interval cuts this down to 1 to 2 years. Here is the thing. Many engineers only look at the battery life number in the datasheet. Weak 4G signal forces the modem to retry. That drains the battery faster than expected.
Silver Instruments configures battery powered meters with NB-IoT, 4G LTE, or LoRa. The data logger can send flow rate, total volume, battery voltage, and alarm states. Some customers also want pulse output for a local totalizer or 4-20 mA HART link. On a battery powered main probe, a 4-20 mA loop needs a separate powered receiver. This matters for remote sites.
Installation Conditions That Trip Up Main Probe Projects
Most engineers skip this part. You need a straight pipe run upstream and downstream of the meter. For a DN100 main probe, allow 5D upstream and 3D downstream when possible. The meter must stay full of liquid. A partially full pipe produces unstable readings. This is common on g

Grounding is another field issue. Electromagnetic meters need a good earth reference. On plastic pipes or internally lined pipes, add grounding rings or use a meter with integrated grounding electrodes.
Silver Automation Instruments Alternative for Battery Powered Utility Main Probes
Silver Automation Instruments supplies battery powered electromagnetic flow meters for water mains, district metered areas, and remote wellheads. The standard configuration uses an EPDM liner, Hastelloy C electrodes, IP68 enclosure, and an internal lithium battery pack. Data options include NB-IoT, 4G, LoRa, RS485 Modbus, and pulse output.
Last year a water utility in Vietnam replaced three insertion probes on a DN200 main. Their problem was not the sensing principle. It was power and data backhaul. We supplied a full bore battery powered electromagnetic meter with a 4G data logger and a small solar charge booster. The meter now sends flow data every 15 minutes and the battery stays above 80 percent after nine months.
What to Send for a Quote
Do not send a request that only says flow meter price. We need four values to select the right meter. Send us your pipe size in DN, operating pressure in bar, water temperature in °C, and minimum to maximum flow rate. Also tell us the data logging interval and the available mobile signal at the site.
If you are replacing a Siemens Mag 8000, include the serial number and the flange standard. We can match the face to face length and drill pattern. This saves re-piping work.

Frequently Asked Questions
Is the Siemens Mag 8000 an insertion probe?
No. The Mag 8000 is a full bore electromagnetic flow meter. It installs between flanges on a water main. The term main probe refers to the measurement point on the distribution main.
What is the minimum water conductivity?
Most battery powered electromagnetic meters need at least 20 µS/cm. Potable water, raw water, and treated effluent normally stay above this level. For demineralized water or very clean rainwater, choose an ultrasonic meter.
How long does the battery last?
At a 15 minute logging interval, expect 8 to 10 years. At a 1 minute interval, expect 1 to 2 years. Poor GSM or NB-IoT signal strength will reduce battery life because the modem retries and draws more current.
Can this meter work in a flooded pit?
Yes. The IP68 housing is designed for submersion. The sensor body and cable entry are sealed. This is why many water utilities bury the meter or install it in a chamber that floods during heavy rain.
Can Silver Automation Instruments match a Mag 8000 face to face length?
In most cases yes. Send us the existing flange standard and serial number. Our team will confirm the lay length and bolt pattern before you order.
