DIFFERENTIAL PRESSURE TYPE SPECIFIC GRAVITY MEASURING DEVICE AND SPECIFIC GRAVITY MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a differential pressure type specific gravity measuring device which achieves the prevention of adherence of a scale and the reduction in a burden of cleaning, and a specific gravity measuring method using the differential pressure type specific gravity measuring device.;SOLUTION: A differential pressure type specific gravity measuring device includes: two blow-off pipes which are provided in a measured liquid and which have outlets at positions differing in distance from a surface of the liquid; pressurized gas generation means which supplies a pressurized gas to the two blow-off pipes and which blows out the gas from the outlets; pressure adjustment means which adjusts a pressure of the pressurized gas supplied from the pressurized gas generation means to the blow-off pipes; two pieces of flow rate adjustment means for adjusting a flow rate of the pressurized gas supplied from the pressurized gas generation means to the blow-off pipes; and pressure measurement means for measuring a differential pressure of the pressurized gas in the two blow-off pipes.;COPYRIGHT: (C)2014,JPO&INPIT
