New screw-in adapters enable easy installation of EGE flow control systems: ST 418, SNS, and SCS probes and compact sensors can now be simply plugged in, aligned, and screwed tight. The adapter is screwed into a T-piece or a welding sleeve. During installation, the plug connector and the LED display can be freely oriented. After that, the sensor is secured in the adapter using a union nut. The connection is reliably sealed up to 100 bar. Various screw-in adapter models which are optionally available allow for universal use of the flow sensors. Standard versions are supplied with a G¼ or G½ thread. The sensors operate according to the thermodynamic principle and are suitable for monitoring liquid flow rates up to 300 cm/s.
