Sparling Instruments adds Modbus support to its electromagnetic flowmeters

Sparling Instruments, a US-based flow and level measurement specialist, has begun production on a Modbus-capable version of its TigerMagEP electromagnetic flowmeter.

Responding to requests from customers for an electromagnetic flowmeter with integrated Modbus for use in digitally controlled or automated systems, Sparling has started shipping the new Modbus version of the meters.

TigermagEP electromagnetic meters, whether integral or remote style, which are already installed in a system can also be upgraded to Modbus by adding an optional Modbus-enabled transmitter or module.

The modules are easy to change out in the field, making the integration of existing TigermagEP mag meters into a Modbus network simple and quick. 

Modbus-programmable mag meters are used in a variety of conductive liquid systems where measurements are digitally reported to a server by the components and recorded for analysis or regulatory compliance.

"We had several municipalities switching to Modbus architecture and asking us to add this protocol to our electromagnetic flowmeters," said Yosufi Tyebkhan, president of Sparling Instruments.

“The Modbus protocol is also used in many other applications, like the oil and gas industry and manufacturing, so that's a lot more customers who will now be able to use Sparling meters," Tyebkhan continued.

The TigermagEP meters are manufactured to exacting standards in an ISO 9001-certified facility, and every meter is tested and certified in Sparling’s on-site flow lab.

The TigermagEP line recently earned NSF 61 certification, meaning it has been approved for installation in potable water systems in all of North America.

Modbus is today's most popular protocol for process control in automation systems.

It was published as open source code in 1979 by Modicon (known today as Schneider Electric) for use with their programmable logic controllers (PLCs).

The Modbus protocol has grown into an international open standard due to the flexibility and simplicity it offers systems engineers.

Unlike other communication protocols, Modbus does not require device description files or other specialised programming in order to create a network that can monitor its component devices.
