摘要: A medical fluid system includes a pump; container holding to be pumped by the pump, at first time having conductivity, second conductivity; and radio frequency level sensor positioned in operable relation with container, operation of configured so as (i) indicative (ii) least substantially independent whether has conductivity or conductivity. The can determine measuring resistance, impedance phase shift seen sensor.
