Krohne Enviromag 2000 Electromagnetic Flow Meter Specifications for Large Water Utility Mainline Magmeters
Quick Answer
Quick Answer: Krohne Enviromag 2000 covers DN25 to DN2000 with hard rubber or soft rubber liners, Hastelloy C electrodes, and accuracy of 0.5 percent of reading. Large water utility mainlines typically use DN600 to DN1600 with PN10 or PN16 flanges, IP68 sensors, and 4 to 20 mA HART. Silver Automation Instruments supplies compatible electromagnetic flow meters with the same process connections and outputs. Send your pipe size, pressure, and flow range for a quote.
Mainline Water Utility Metering Requirements
Large water utility mainlines move raw water from dams, treatment plants, and reservoirs into distribution zones. The meters on these lines usually sit in buried vaults or direct burial installations. The sensor can stay under water during heavy rain or high groundwater. That is why many utilities specify IP68 protection and a remote converter mounted above grade.
Typical line sizes for mainline meters range from DN400 to DN2000. In practice, DN700, DN900, DN1200, and DN1600 show up often in water supply projects. Flange ratings are normally PN10 for treated water and PN16 for raw water or booster station discharge. Meter liners need to resist abrasion from sand and silt. Rubber liners handle this well in clean water and raw water applications. We have seen this on customer sites in Manila and Ho Chi Minh City.
Key Krohne Enviromag 2000 Specifications
The Enviromag 2000 is a full bore electromagnetic flow meter. Below are the core specs engineers check before shortlisting a supplier.
- Line size: DN25 to DN2000
- Liner: hard rubber for potable water or soft rubber for raw water
- Electrodes: Hastelloy C
- Accuracy: 0.5 percent of reading above 0.5 m/s
- Output: 4 to 20 mA with pulse, HART optional
- Power: 85 to 250 V AC or 24 V DC
- Protection: IP67 standard, IP68 optional for flooded vaults
- Flange: EN 1092-1 PN10 or PN16
- Flow direction: bidirectional measurement
These specs match most potable water, raw water, and reclaimed water mainlines. The full bore design has no moving parts and no pressure drop. That matters on gravity fed water lines where head loss is limited. Most engineers skip the flow conditioner because electromagnetic meters do not need one.
Signal Output and SCADA Integration
Water utility control rooms need flow rate and total volume on SCADA. The standard 4 to 20 mA analog signal sends instantaneous flow. A pulse output sends totalized flow to a remot

A water authority in Vietnam recently asked for DN900 meter with Modbus RTU, IP68 sensor, and a 20 meter signal cable. The meter feeds data into a Schneider PLC. The install crew wanted a remote converter because the vault floods every monsoon season. This is a typical mainline metering job.
Silver Automation Instruments Compatible Magmeters
Silver Automation Instruments supplies electromagnetic flow meters for water utility mainline service. Our range covers DN25 to DN2200 with rubber liner, PTFE liner, stainless steel electrodes, and Hastelloy C electrodes. We quote 4 to 20 mA HART, pulse, Modbus RTU, and Profibus DP. Pressure ratings include PN10, PN16, and ANSI 150.
Do not send only the brand and model. Send the exact tag plate data from your existing Krohne Enviromag 2000. Include line size, flange rating, liner material, electrode material, power supply, and signal output. Also add your normal and maximum flow rate in m3/h. We will quote a compatible meter with the same face to face dimension if possible.

Frequently Asked Questions
Can Silver Instruments supply a direct replacement for Krohne Enviromag 2000?
Yes. We supply electromagnetic flow meters with the same line size, liner, electrode, and signal output. Send your existing tag plate details for a formal quotation.
What is the typical lead time for a DN1000 water mainline magmeter?
A DN1000 meter with rubber liner and IP68 sensor normally ships in 4 to 6 weeks ex works. If the flow range needs special calibration or a pigging sensor, allow 6 to 8 weeks.
Does the meter need a long straight run?
Standard installation requires 5D upstream and 3D downstream. D means pipe diameter. For a DN900 line, that is 4.5 m upstream and 2.7 m downstream. Confirm your piping layout before you order.
Can the sensor be buried or installed in a flooded vault?
Yes. Use an IP68 sensor and install the remote converter above the flood line. Signal cable lengths of 10 m, 20 m, and 30 m are common. Longer cables are possible on request.
What is the common power supply for water utility mainline meters?
Most pump stations use 85 to 250 V AC. Remote sites with solar power use 24 V DC. Confirm your available supply before finalizing the order.
