Endress+Hauser Proline Promass 300

Name: Endress+Hauser Proline Promass 300
Brand: Endress+Hauser
SKU: 620c8f78-a02c-4662-94be-bd7047b2beb5

Coriolis flowmeter that measures mass flow, volume flow, density and temperature of liquids and gases.

The Endress+Hauser Proline Promass 300 is a Coriolis flowmeter that measures mass flow, density and temperature of liquids and gases directly in the pipe. This Modbus RTU template reads flow, density, temperature, totalizers and diagnostics, and lets you change units, damping, low flow cut off and totalizer settings from ModbusCloud.

Protocol: Modbus RTU
Connection: RS485, 19200 baud
Registers: 655, read and write

Brand: Endress+Hauser
Key readings: Mass flow · Volume flow · Density · Temperature · Totalizers · Diagnostic messages · Corrected volume flow
Available commands: Engineering units · Damping · Low flow cut off · Totalizer reset · Output settings
Compatible models: Promass A 300 · Promass E 300 · Promass F 300 · Promass H 300 · Promass I 300 · Promass O 300 · Promass P 300 · Promass Q 300 · Promass S 300 · Promass X 300

Send your device list

If a device is not in the library yet, we build the template for free as soon as we have the register data.

Use cases

Show mass flow, density and temperature on a dashboard per production line.
Log totalizer values every day to report consumption per batch or per month.
Raise an email alarm when the actual diagnostic code is not zero.
Alert when density leaves its normal band, a sign of air or a wrong product in the line.
Change the mass flow unit or the damping remotely without opening the transmitter.
Compare electronics temperature and Heartbeat results over a year of history.

Installation

Connect RS485 A and B of the Modbus I/O module to the RS485 port of the ModbusCloud Gateway, and terminate both ends of the bus.
On the device, check under Communication that the bus address, 19200 baud, even parity and byte order 1-0-3-2 are set.
In ModbusCloud, add a Modbus device with the same address and serial settings and import this template.
Check that mass flow and temperature show plausible values; a zero flow at a running pump points to the wrong address or byte order.

Things to watch for

The flowmeter does not answer. What should I check?

Check the address (factory 247), 19200 baud and even parity on both sides, then swap A and B. Make sure the bus is terminated at both ends and that only one master polls the device.

Why do the flow values look like huge or tiny random numbers?

The float word order does not match. With the factory byte order 1-0-3-2 the template reads correctly. If someone changed the byte order on the device, set it back under Communication.

Some registers always read zero. Is that a fault?

Not always. Values such as concentration, viscosity, pressure or the petroleum values only exist with the matching order option or configuration. Without that option the device returns zero or rejects the read.

Is it safe to write settings from the portal?

Yes, but sparingly. Every write to a setting is stored in the EEPROM of the device, which allows about one million write cycles. Do not write settings from an automation that runs every few minutes, and check the access code if the device refuses writes.
