Seametrics Authorized Distributors are trained and very knowledgeable of all Seametrics products. Please contact a distributor to get detailed case-by-case applications support.
What is conductivity and why do I need to know this when using a magmeter?
Conductivity refers to the ability of a material to transfer electrical potential. This value is typically measured in microSiemens per centimeter. Seametrics magmeters require a conductivity of at least 20 mS/cm in order to operate properly.
How does an electromagnetic flow meter work?
This video illustrates the difference between mechanical and electromagnetic flow meters.
Why can’t I use my MJ meter with a Seametrics Display unit?
The FT400 Series displays require a frequency of at least 1 Hz in order to operate properly and the MJ and WJ Series meters typically do not provide a pulse frequency that exceeds 1 Hz. Therefore Seametrics does not recommend using the MJ or WJ units with Seametrics display units. MJ and WJ meters are …

Which meters are compatible with the chemicals in my process?
Check our Seametrics Chemical Compatibility Database to see if the chemicals in your process are compatible with Seametrics meters. If you cannot find your chemical in our database, we recommend checking Cole Parmer’s Database or other external resources.
Why is it important to meet the straight pipe requirements?
Without proper straight pipe before and after the flow meter, the profile of the flow will not be smooth and a proper reading of the flow rate cannot be measured. For specific straight pipe requirement please reference the appropriate instruction manual or technical bulletin.
Is viscosity of my fluid going to cause any issues with a Seametrics meter?
Typically, as long as there is enough pressure in the line to push the fluid through the line, your Seametrics flow meter should function. For mechanical meters, if the fluid’s viscosity is substantially different from the viscosity of water (0.894 cP) you will need to field calibrate your Seametrics meter. For electromagnetic flow meters, the …

What type of output signals do Seametrics meters have?
With the exception of the MJ and WJ units, most Seametrics products have a current sinking pulse output. This is often referred to as an open collector or NPN signal. The FT420 and AO55 units also have analog output capabilities.
How do I determine if other equipment is compatible with a Seametrics unit?
The quickest way to determine this is by doing the “tap test.” If you can make your pump operate or your display count up by tapping the two input terminals together with a jumper wire, then the unit should be compatible with your Seametrics unit.
What is the difference between a digital and analog output?
A digital signal is discreet which means you only get a signal at set intervals while an analog signal is a continuous waveform.
