Connection to Different Bus Systems Options

N/A There are different options available for connection to modern Bus systems:

Ethernet interface (Modbus-TCP) / PoE
M-BUS
Modbus-RTU
Ethernet Modbus TCP
M12 Ethernet port, x-coded

With a Key Stroke

N/A

Reset counter reading
Select units
Zero-point adjustment, leak flow volume suppression

Options

N/A Bi-directional measurement. Blue or green arrows in the display indicate the direction of flow.
A meter reading is available for each flow direction.

Application-Technological Features

N/A

Digital interfaces such as Modbus-RTU, Ethernet (PoE) and M-Bus enable connection to higher-level systems such as energy management
Systems, building management systems, PLC
Easy and affordable installation
Units freely selectable via keys on the display CF, lbs, CFM
Compressed air counter up to 1,999,999,999 m³ can be reset to Inch (in)zero Inch (in) via keypad
Analog output 4 to 20 mA, pulse output (electrically isolated)
High measuring accuracy even in the lower measuring range (ideal for leakage measurement)
Negligibly small loss of pressure
Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
Comprehensive diagnostic functions can be read out on the display or remote access via Modbus-RTU such as exceeding max./min
values ºF, calibration cycle, error codes, serial number. All parameters can be read out and changed via Modbus

Additional Information

N/A Modbus-RTU output
4 to 20 mA output for present flow

Pulse output for total flow (counter reading), galvanically isolated or M-Bus (optionally)

New: Integrated pressure sensor (optional)

Measuring unit can be unscrewed: Removal of the entire measuring section not necessary, no by-pass necessary

Easy installation into the existing pipeline due to integrated measuring section and weld neck flange (according to EN 1092-1 PN 40)

High measuring accuracy due to defined measuring section (inlet and outlet section)

Display head rotatable by 180º e.g. in case of reverse flow direction

The sensor can be removed and cleaned.
