Q: What is the Maximum limit of flow which can the FMA-1900 pass?
A: The FMA-1900 is manufactured to pass a maximum flow rate measuring 0-50 standard litres of liquid in one minute.
Q: Which output signals does FMA-1900 give?
A: The signals are linear 0-5 VDC and 4-20 mA output signals.
Q: What is the power supply that is needed to run the FMA-1900?
A: The power supply needed for the FMA-1900 is 24 VDC and is regulated with least 6 watts (250mA) @ 24 VDC +10%.
Q: With which gases can FMA-1900 be used?
A: Many gases can be used with FMA-1900 such as air, nitrogen, methane, carbon dioxide, argon, helium, and hydrogen.
Q: What to do in case FMA-1900 goes to overrange condition ?
A: An overrange condition, is when the display or output reaches the maximum limit of its full scale range. The FMA-1900 will take time extending to up to several minutes to get back to normal functionality after the overrange condition is removed.
Q: Is FMA-1900 a loop powered device?
A: No, FMA-1900 do not fall in the category of loop powered devices.
Avoid connecting power on the input or output of the 4-20 mA section.
Q: What is the accuracy percentage of FMA-1900?
A: It could be seen that the accuracy percentage of FMA-1900: ±1.5% of full scale between 10 – 100% of full scale.
Q: What is the FMA-1900 installation procedure?
A: Ensure that the FMA-1900 instrument is clean and has the right plumbing fittings before it is fixed. Also ensure that the arrow on the transducer is in the correct position so that it indicates the flow direction.
