Model OVAL D
Introduction

OVAL D measuring station is designed and developed to monitor oil flow rates measured by model SR -oval gear meters in circulation lubrication systems.

The OVAL D measuring station(s) can be as an independent station(s), connected to Kytola KVMWIN control room software or to customers DCS / PLC via Modbus RTU protocol.

Features Stainless steel housing  Local display Serial interface RS485 or RS422 Communication with upper level systems Modbus RTU protocol Kytola KVM protocol Alarm relays Alarm inhibits Alarm groups              Typical applications Lubrication oil monitoring Industrial oil flow monitoring Process control
