Q: Can I wire a Max Flow Meter with an analog transmitter to loop power (2-wire) or a non-isolated (3-wire) system?
Max: We have many customers using Max Precision Flow Meters with the 4-20 mA Analog transmitter option that ask about alternative wiring methods to the standard 4-wire fully isolated installation shown in the manual. To download the manual for you meter, go to www.maxmachinery.com/downloads and select the manual for your meter from the list. Here is the wiring diagram from the manual:
Max Precision Flow Meters are designed to be in a fully isolated electrical system for optimum performance and maximum data transfer with the least electrical interference that is possible.
If your system is not designed to take advantage of the maximum performance of your Max Flow Meter and the cost to upgrade is prohibitive, Max Meters can be used in a non-isolated (3-wire) system. Max Flow Meters will not operate in a 2-wire or loop powered system as the power requirements for the meter exceed loop power specifications. For non-isolated systems where a single ground is provided, follow the diagram below to wire in any Max Flow Meter with an analog transmitter:
Once you have confirmed your system is providing measurement data, be sure to verify and filter out the noise that will occur due to the shared ground. Depending upon the data stream, the application environment, and the other equipment in use, the interference may be none, little, or significant.
If you are still having trouble with the data you are collecting, you may always reach out to Max Machinery or one of our sales partners for free technical support. Click Here to Contact Us.

Max Machinery is pleased to announce the upgraded F381 filters to our line of accessories. Instantly recognizable as a compact, round in-line filter, this new version of our classically square filter now provides contamination protection up to 70 Liters/minute at 3000 psi.
For over 25 years, Max Machinery has been providing protection for our piston and gear meters that operate in lower pressure ranges. As our flow meters have been upgraded and improved to be more robust and operate at higher pressures, we are making sure our filters can protect your customers’ systems from contamination at those same high pressures.
The F381 series of filters are based on a single round body size rated at 3000 psi that allows flow rates up to 70 Liters/minute and has 5, 10, and 30 micron filtration size ratings and 4 sealing options for a broad range of process fluid chemicals. The 303 stainless steel body has three port options of 3/8” NPT, #6 SAE, and 3/8 BSPP. O-ring seals are Viton® standard and may be optioned to Teflon®, Neoprene, or Perfluoroelastomer (FFKM).
With such a significant base of square 381 filters operating at customer locations around the world, we wanted to make future filter element kit replacements as easy as possible. Both the old style 381 square filters and the new round body F381 filters use the same replacement kits. This frees your replacement order process from mistakes. If you have all 381 square body filters, all F381 round body filters, or a mix of both body styles, the same filter element kits will fit and have your system protected against contamination.
Max Machinery also engineered the new F381 filters to be cost efficient. Even with the performance improvements, the F381 filters start at the same price you come to expect for Max filters. Filter element kits also maintain their prices.

For high volume orders or customer specific customizations, contact Max Machinery directly to discuss the opportunity.
