MODBUS-Based Flow Metering and Pressure Monitoring
The Preciseline Pressure Transducer (manufactured by Keller-America ), not unlike our EtherMeter, offers a digital Modbus-based solution to a water telemetry problem that was previously solved by analog (4-20mA) instrumentation.
Preciseline Pressure Transducer (by Keller-America).
In the case of the Preciseline, the water pressure signal is converted into Modbus; whereas in the case of our EtherMeter, error-free [...]
Application Notes: Data acquisition with the Trimble Nomad & Keller DCX data-logger
Prerequisites:
1) A Trimble Nomad (or similar Windows Mobile1).
2) RS232 port boot option (USB interfaces are not supported for the Logger CE software).
3) Keller DCX series data-logger
4) Keller K-103A RS232-to-RS485 converter
Notes:
1 While Keller data-loggers and interface converters will theoretically work with any Windows Mobile device that supports a physical RS232 communications port, due to the myriad [...]
Guide to using Keller Level & Pressure transmitters with the Precision Digital PD865
This guide will help walk you through the configuration required to use a Keller MODBUS-capable level or pressure transmitter with the Precision Digital PD865 display. Jose, from Precision Digital, recently made video using this very same configuration, which you can watch here.
So just what is the PD865? The PD865 (also called ‘Snooper MODBUS Meter’) is [...]
