## Overview

Turbine flow meter delivering precise measurement of liquids with high accuracy, good repeatability and reliable industrial performance.

## Description

### Product Overview

The RBLTF turbine flow meter measures clean and low-viscosity liquids with accuracy up to ±0.2% and short-term repeatability of 0.05–0.2%. Pulse-frequency output gives strong anti-interference performance for long transmission distances to counters, PLCs or DCS.

Compact and lightweight, the RBLTF is available in threaded, clamped and flanged connections as well as insertion versions for large pipes, with an optional explosion-proof ExmIIT6 variant for hazardous areas.
