Sealed buffer tank

● Device：Sealed buffer tank
● Medium: Formaldehyde
● Temperature：70℃
● Pressure：1.0MPa
● Density：807kg/m³
● Output Signal：4-20mA+HART
● Short measurement range, drift in double flange measurement results, inaccurate measurement, needs to be reset to zero in about 2 weeks

● Solve the problem of liquid level fluctuation caused by dual flange in short range measurement .
● Actually, it is recommended to use Magnetostrictive Level Transmitter within 1 meter, because most of the differential pressure generated within 1 meter is within 10kPa. For Differential Pressure Transmitters, the range is small, and the double flange level transmitter is affected by environmental temperature and static pressure, resulting in large errors and inaccurate measurement, requiring frequent zeroing.
