Piston inline flow transmitter

OMNIPLUS-HR2

Flow transmitter for water flow monitoring up to 300 l/min

Introduction

Higher water flow rates need measurement that fits industrial pipework without making the installation more difficult. This transmitter family measures water from 5 ... 300 l/min in DN 32, DN 40 and DN 50 sizes and requires no inlet or outlet runs.
 
The spring-supported variable area principle gives the measurement a robust mechanical basis. A magnet-equipped float moves against a spring as the medium flows, while magnetic field sensors detect its position outside the flow chamber. Female threads from G 1¼ to G 2, 8 % full-scale accuracy and approximately 1 bar pressure loss at Qmax support practical use in water circuits.
 
Integration is supported by one configurable analog output, two switching outputs and IO-Link V1.1. PS 200 pressure resistance, IP65/IP67 protection, brass or stainless steel versions and an optional +120 °C media temperature range with distance pieces make the family suitable for demanding industrial applications.

Features

Spring-supported measuring principle

The transmitter uses a spring-supported variable area principle. A magnet-equipped float moves with the flow, and magnetic field sensors detect its position outside the flow chamber.

Nominal sizes and ranges

The product family covers DN 32, DN 40 and DN 50 with measuring ranges from 5 ... 60 l/min up to 25 ... 300 l/min for water.

Mechanical connection

The devices use female threads from G 1¼ to G 2. Further connection types are available on request according to the source.

Analog output

The analog output can be configured for current or voltage, including 4 ... 20 mA, 0 ... 20 mA, 0 ... 10 V, 2 ... 10 V, 0 ... 5 V, 1 ... 5 V and 0.5 ... 4.5 V.

Switching outputs

Two push-pull transistor outputs can be set as limit switches, frequency outputs, pulse outputs or outputs for the preset counter.

IO-Link communication

The device supports IO-Link V1.1 with COM2 transmission, SIO mode, block parameterization and data storage.

Display and alarm indication

The graphical 1.2 inch LCD has 128 x 64 pixels and uses white backlighting in normal operation and red backlighting for alarm messages.

Material and options

The family is available in brass and stainless steel versions, with an optional extended temperature range to +120 °C using distance pieces.
