High performance, Dia-shape bluff body and insertion type: EX DELTA
DELTA FLOWMETER can be used for gas, liquid, or steam flow. The total absence of any moving parts, low pressure loss, ease of use, and long life use with outstanding repeatability - all these desirable characteristics make it well suited for calorific transaction control and many other applications. Of EX DELTA series, the smart type features self diagnostics and capabilities to review and change parameters, while EX DELTA-DIA is compatible with “dirty” processing full of contaminants; EX DELTA-SS saves space combined with a battery powered EX DELTA dedicated for the task of local monitoring.
The sensor in each model essentially comes in two styles - the standard fixed sensor and the replaceable sensor which permits servicing without removing the meter from the pipeline. The VF series features a high-sensitivity sensor for gas service and the Flow Monitor, accommodated in a synthetic resin molded housing, is ideally suited for flow metering at the end use.
