Product Specifications

Yes. There are chemicals that will not work with the MS6, specifically sodium hydroxide, sulfuric acid, and neat polymers. Chemicals must be acoustically conductive and contain particulate less than 50,000 ppm. 

No. The MS6 will not work with caustic soda - NaOH - Sodium Hydroxide.

Yes. The MS6 flow meter enclosure is rated NEMA 4X, and has IP66 rating. 

Yes. The MS6 flow meter is NSF 61 Listed.

The MS61 model can read flows as high as 5,000 ml/min (79.2 gph). The MS62 model can read flows as high as 10,000 ml//min (158.5 gph)

The MS61 model can read flows as low as 10 ml/min (.158 gph). The MS62 model can read flows as low as 100 ml//min (1.58 gph)

The MS6 Flowmeter has been tested with a number of chemicals, some of which are listed on the Datasheet. For other chemicals, we recommend contacting the factory with SDS sheet and process information. We will be able to advise on compatibility based on previous feedback or chemical make-up. An option to buy and trail a unit may be available. 

The MS6 meter can measure chemicals with bubbles and particles provided the bubbles and particles are not so large, or numerous, as to block the ultra-sonic sound beam. For example, the MS6 functions very well measuring sodium hypochlorite. The MS6 meter takes many measurements per second, so while small bubbles and particles can reduce the number and quality of the measurements, the meter is still able to take enough measurements for an accurate reading. Installing a strainer/filter directly before the MS6 can break up large bubbles and filter out particles.  

The sensor will work with acoustically conductive fluids with particulate and bubbles 50,000 ppm or less. A list of Pre-Configured (factory-tested) chemicals is available in the product datasheet, and includes: 

• Water
• Aqueous Ammonia 10%
• Ammonium Hydroxide 30%
• Ferric Chloride 40%
• Sodium Bisulfite 40%
• Sodium Hypochlorite 12.5%
• Sodium Permanganate 40%
• Hydrofluorosilicic Acid 25%
• Ammonium Sulfate 10%

Additional approved (non factory tested) chemicals are:

• Alum
• Ferric Chloride
• Chemicals that can’t be used:
• Sodium Hydroxide
• Sulfuric Acid
• Neat polymers

Different chemicals have different accuracies in an ultrasonic meter because they have different acoustic properties. Acoustic properties are the physical properties of a material that affect the way sound waves propagate through it. Some of the most important acoustic properties for ultrasonic flowmeters are the speed of sound, the attenuation coefficient, and the density. The speed of sound in a fluid is the distance that a sound wave travels in a unit of time. The speed of sound is affected by the temperature and pressure of the fluid, as well as the composition of the fluid. The attenuation coefficient is a measure of how much sound energy is lost as it travels through a fluid. The attenuation coefficient is affected by the composition of the fluid, as well as the frequency of the sound wave. The density of a fluid is the mass per unit volume. The density of a fluid affects the way sound waves propagate through it.

We do not have exact data at this time but Ultrasonic flowmeters are generally very repeatable. The repeatability of an ultrasonic flowmeter is affected by a number of factors that include the type of fluid being measured and the installation conditions.

A component of a metering pump or flowmeter that comes in contact with the fluid being pumped or measured is considered a WETTED FITTING or WET COMPONENT. Examples include O-ring seals, gaskets, inlet and outlet fittings, diaphragms, valve components, etc. 

The term TRUE UNION is used to define a flowmeter with double unions, on the inlet and outlet side of the flowmeter, that allow for servicing of the flowmeter, whether you are cleaning, repairing, or replacing the flowmeter. The main portion or “body” of the flowmeter can be taken out of line for ease of service without disassembling the entire system.

The properties of the materials used in the flowmeter can contribute to pressure changes with temperature. For example, certain materials used for seals, gaskets, or O-rings may experience thermal expansion or exhibit decreased elasticity at higher temperatures. This can result in leaks or reduced sealing effectiveness, leading to pressure loss.

NEMA 4X is a rating for enclosures that indicates they are designed to provide protection against corrosion, windblown dust and rain, splashing water, and hose-directed water.
