E-Series Explosion Proof Flow rate Indicators / Totalizers
These unequaled explosion-proof flow computers deliver user-friendliness in the toughest conditions.
Advantages
- Saves time and improves flexibility with the through-glass keypad: no need to open the front cover.
- Familiar easy operation with the Fluidwell “Know one, know them all” configuration structure, saving time, cost and aggravation.
- Durable high-grade stainless steel 316L Ex d enclosure withstanding extreme (maritime) conditions.
Signal Input
Flowmeter Inputs
- Pulse-type inputs:
Reed-switch, NAMUR, NPN/PNP pulse, Sine wave (coil), active pulse signal. - (0)4 – 20mA.
- 0 – 10V DC.
Status Input
Remote control: external input for clearing total or to disable manual clearing by the keypad.
Signal Outputs
Pulse outputs
