Marmonix MFU-6300 Wall-Mount Transit-Time Flow Meter

The Marmonix MFU-6300 ultrasonic flowmeter is a fixed, wall-mounted transit-time flow meter for liquids: the transmitter fits indoors, in an instrument cabinet or on a dashboard, and the transducers go on pipes from DN15 to DN6000. It is better than ±1% accurate, gives 4–20 mA, OCT pulse, relay and isolated RS485 outputs, keeps cumulative flow for the last 512 days, 128 months and 10 years, and measures heat flow with three-wire PT100 sensors. Browse all Marmonix flow meters, or see the MFU-6000 handheld clamp-on flowmeter for portable checks.

Questions about the MFU-6300 ultrasonic flowmeter

Can the MFU-6300 measure heat or energy?

Yes, the MFU-6300 measures heat flow when you connect three-wire PT100 platinum resistance temperature sensors; its datasheet lists clamp-on and insertion PT100 types for pipes from DN50. Its three 4–20 mA inputs can also collect temperature, pressure or level signals.

What installation does the MFU-6300 need?

The MFU-6300 needs a straight pipe run of 10 diameters upstream and 5 downstream, at least 30 diameters from a pump outlet. It works on steel, stainless steel, cast iron, copper, PVC, aluminium and FRP pipes (lined pipes allowed), and the transmitter runs on DC 8–36 V or AC 85–264 V at 1.5 W.

MFU-6300 or MFU-6000: which should I choose?

Choose the MFU-6300 for permanent metering with 4–20 mA, pulse, relay and RS485 links to a control system, and the MFU-6000 handheld for portable spot checks on different pipes. Both use the transit-time principle and cover pipes from DN15 to DN6000.

Case study: permanent flow and heat monitoring in water systems

In a typical installation, running water, heating networks and industrial plants need continuous flow data for water balance testing, network commissioning and energy monitoring.

A fixed ultrasonic flowmeter mounts its transmitter on a wall, in a cabinet or on a dashboard, with transducers fitted on the pipe. It measures flow by transit time, and with PT100 temperature sensors added on supply and return, it also calculates heat flow.

Engineers wire the 4–20 mA, pulse, relay or RS485 output to the control or energy management system. Daily, monthly and yearly totals stored in the meter make it easy to compare consumption between periods and to spot changes that point to leaks or imbalance.
