What type of flow meter is suitable for measuring the graywater flow rate in coal-to-hydrogen processes

Electromagnetic or flange differential pressure? Which is more suitable for graywater
What is graywater? Is it water containing fine ash?
Electromagnetic solutions offer great cost-performance! But the wear resistance of the measuring electrode must be taken into consideration. Is the wedge flow meter the appropriate measurement method for flange differential pressure? I think the wedge flow meter is more stable and easier to use.
The coal-to-hydrogen process is a method for producing syngas through the combustion reaction of oxygen and coal slurry; the coal slag is cooled with quench water before being discharged, and there are two types of water: black water, which contains more coal slag, and gray water, which contains less coal slag
The process pipeline is 4 inches in diameter; slag tends to form at the flanges, and it needs to be removed regularly, so I want to replace it
Using a wedge flow meter, and a double-flange differential pressure transmitter with an adamantium diaphragm from Far East Instruments
It operates stably, and the transmitter has a long lifespan. Previously, gold-plated diaphragms were completely unsuitable for measuring gray water and black water; after switching to the new type of diaphragm, they can generally last for over a year
It’s better to use electromagnetic methods; the measurement of water-coal slurry is done using electromagnetic techniques.
We also use electromagnetic flowmeters for our coal slurry, but they are from Coriolis; the cost is too high
