KTR-550B / KTR-550F  is an indicator controller dedicated to Turbine flowmeters. It is designed to input the K-Factor proportional to the flow rate by directly connecting the frequency (Hz) generated by the drive part of the turbine flowmeter without going through any converter.

Simple system can be constructed by adding instant flow, accumulated flow, High⦁Low Contact, and Batch functions. The design is simple and compact and can be mounted on the panel.
