Product information

Specifications

Description

FLOWSIC600 DRU-S is a compact and innovative ultrasonic gas flowmeter for gas production. The gas meter is specifically designed for wellhead and gaslift applications. With a measuring range of more than 1:100, the FLOWSIC600 DRU-S covers flow ranges that previously required several orifice plates. Its special "wet gas robust" design ensures continuous measurement even under continuous high liquid loads. FLOWSIC600 DRU-S allows remote monitoring of measurement and diagnostic data.

Field of application

Natural gas measurement in gas production
Associated gas measurement in oil production
Wellhead and gaslift measurement
Raw natural gas measurement at gas treatment plants (VRU, VRT, dehydration units, etc.)

Device properties:

Designed for wet gas applications
No pressure drop
High turndown ratio ≥ 100:1
Operates from atmospheric pressure
New diagnostic feature – Liquid indication
Plug & play connection to Monitoring Box for remote diagnostics

Benefits

Highly reliable – continuous gas measurement even in wet and dirty process conditions
Low initial investment - accurate measurement without expensive flow calibration
Elimination of scheduled maintenance with real-time remote diagnostics
Advanced process monitoring capability with unique liquid detection
Long life - wet gas resistant titanium ultrasonic sensors
Quick and easy commissioning through FLOWgate™
