ES-FLOW Series, Low Flow Ultrasonic Flow Meters and Controllers

ES-FLOW Series, Low Flow Ultrasonic Flow Meters and Controllers

Product Overview

The ES-FLOW Series of ultrasonic flow meters are volumetric liquid flow meters for very low flow ranges. These instruments operate on an innovative measuring principle using ultrasound in a very small, straight tube. A wide range of liquids can be measured independent of fluid density, temperature, and viscosity.
Liquid Independent Measurement of Low Volume Flow Rates

  • Lowest range 2 … 100 ml/min
  • Highest flow approx. 1500 ml/min, depending on e.g. the available pressure drop

Description

  • Innovative sensor with fast response time and high accuracy
  • Low pressure loss due to the straight stainless steel tube
  • Dosing with integrated PID controller
  • Compact control solutions using a valve or a pump
  • Direct volume flow measurement, independent of fluid properties
  • Hygienic design with capacitive touchscreen
  • IP66 and IP67 rating and CIP cleanable

Applications

ES-FLOW Series Low Flow Ultrasonic Flow Meters and Controllers Model Line-Up

Liquid Flow Meters

Due to the combination of a straight sensor tube with zero dead volume, self-drainability, orbital TIG-welding and hygienic connections, this flow meter can be used for hygienic applications. Wetted parts are made of stainless steel, except for the rubber gaskets at the Triclamp or flange connections. The exterior design is according to IP66 as well as IP67. For non-hygienic applications, the instruments can also be equipped with compression type fittings.

The user interface is a capacitive touchscreen with a TFT display to operate and readout the instrument.

Liquid Flow Controllers

The liquid flow meter can be connected to a dosing pump or a control valve to form a closed control loop. The electronic control function forms part of the normal circuitry in the meter.
