High Accuracy and High Resolution,with 2-Wire 4–20 mA Output

FGY1000 Series
Magnetostrictive Level MeterOUTLINEThe FGY1000 is a magnetostrictive level meter that pinpoints a float
position using a magnetostrictive sensor, enabling high-accuracy,
high-resolution level measurements.
The level of various liquids is output as a 2-wire, 4–20 mA DC
signal, and a HART communication function comes as standard.
The FGY1000 can be used safely under harsh conditions suchas corrosive liquids and pressurized or vacuum tanks, because
the magnetostrictive sensor is completely insulated from theatmosphere in the tank by a rigid pipe or flexible tube.

STANDARD SPECIFICATIONSType of detection: Magnetostrictive

Pressure class: JIS5K to JIS20K, ASME#150 to ASME#300

Liquid temperature: −40ºC to +125ºC			 Depends on the material and temperature			class.			 See Table 1 for details.
Process connection: Tank top flange: 50A (2") or larger			 Outer chamber flange : 20A (3/4") or larger			 Inner chamber flange : 80A (3") or larger			 See Figures 3 and 4 for details.			 Ferrule: 2.5S to 6.5S
Two-liquid interface detection		: Density difference must be at least 0.2 g/cm3.

Ambient temperature : Operation: −40ºC to +70ºC			 Explosionproof: −40ºC to +60ºC			 Storage: −45ºC to +80ºC			 Depends on the temperature class.			 See Table 1 for details.
Ambient humidity: Operation: 0 to 95% R.H.			 Storage: 0 to 85% R.H.
