flange liquid-level Transmitter

1) characteristic:
    LU-CLT may accurate measure liquid & density which in each kind of vessel. There are flat-flange & in-line-flange,and size is 3 inch(3'') or 4 inch(4''),specification is 1501b or 3001b,may special make for user's requirement. If no indication,our company will diliver the flange of 3'' & 1501b, Flange diaphragm material may be selected.

2)Technical performance

2.1 to subject: liquid in breached or seal container
2.2 range ability: please contact us
2.3 output: 4-20mA DC
2.4 power: 24VDC, it can be 12VDC if non-load, max. is 45VDC
2.5 indicate meter(field):scale gauge length:30mm,grade:2.5
2.6 isolating explosion:ds II BT5; instrinsically-safety:ia II CT5
2.7 positive & negative transfer: up and low may not exceed the range limit after positive & negative transfer,whatever the output is.
2.7.1 Max.positive transfer:500% of the min.span.
2.7.2 Max.negative transfer:600% of the min.span.
2.8 span and zero: external continually adjusted
2.9 temperature:
2.9.1 temperature of operating for amplifer:-25 degree to +90 degree
2.9.2 temperature of operating for sensor:-40 degree to +104 degree
2.10 relative humidity:0-100%
2.11 sensor capacity changes:<0.16m^3
2.12 static-pressure and over-pressure limit2.12.1 1501b flange:42Kpa (Ap) to 1.9Mpa(37 degree)
2.12.2
 3001b flange:42Kpa (Ap) to 4.9Mpa(37 degree)
2.13 damp:continually adjusted when time constant is between 0.2-1.67s
2.14 setting time:2s

3) performace index (Note: test under the condition of none shift, max. range status of sensor, 316L stainless isolating

disaphargm and other standard condition)

3.1 Accuracy:0.25% of the span, including the synthesize errors of linear, change-difference and repeat.
3.2 Stability:0.25% of max. range (12 months)
3.3 Temperature affect:
     Zero error:0.75% / 55 degree, total errors:1.5%/ 55 degree, when max. range;
     Zero error:4.5% / 55 degree, total errors:5.25% / 55 degree, when min. range;
3.4 static-pressure affect:zero error < 0.5% of max. range,when add 4 Mpa(AP); range error is system error, can be calibrated.
3.5 vibration affect:0.05%/g of the max.range,when 200Hz, any axis up.
3.6 power affect:<0.005%/V of output range
3.7 load affect:none affect when voltage>12VDC input to the transmitter
