测量原理热式
产品标题Insertion flowmeter with long-term stability and a compact, easily accessible transmitter. Flexible, convenient programming based on 21 standard gases or freely definable gas mixtures thereof. Measurement of utility and process gases as well as gas mixtures in circular piping or rectangular ducts.
传感器特点High level of process control – premium measurement accuracy and repeatability. Reliable monitoring – detection of process disturbances and reverse flow. Flexible installation – suitable for large dimensional range and circular pipes or rectangular ducts. Insertion version for DN 80 to 1500 (3 to 60"). Bidirectional measurement; high measuring performance. Patented drift-free sensor with SIL 2.
变送器特点Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology. Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access. Remote display available.
