New flow monitor provides advanced controls with easy field setup
US-based flow solutions provider Badger Meter has introduced the new Blancett B2900 flow monitor offering advanced digital signal processing technology in an easy-to-access package.
Enclosed in a spacious polycarbonate NEMA 4X housing, the electronics are located on a single board, designed for straightforward and convenient field installation.
The large enclosure provides more room for the user’s hands and tools when wiring the monitor in the field.
The B2900 enclosure features an LCD display with push button programming as well as a pre-drilled hole for external wiring connections, such as Modbus RTU and other outputs.
The monitor processes a frequency output from a flow sensor and interprets the signal to calculate flow rate and total flow simultaneously with 10-point linearization for improved accuracy.
The B2900 is well-suited for use with low-level frequency input signals, and it can be used with almost any flow sensor producing a low amplitude AC output or contact closure signal.
It provides advanced communication capabilities over an RS485 bus using Modbus RTU and control outputs, allowing operators to connect meters to a network for process automation and/or remote flow monitoring.
The Modbus RTU connection can be configured with user-selected baud rates.
To ensure security in remote applications, robust alarm parameters provide faster warning when something changes in the process or pipeline, and the keypad display can also be password protected to prevent unauthorised tampering.
An added benefit for remote monitoring applications is that the B2900 monitor can be configured for both loop power and battery power, with the battery rated for a six-year lifespan.
The battery also acts as a backup power source in the event of loop power loss or interruption.
B2900 flow monitors are hazardous location certified (Class I Division 1, Groups C, D; Class II, Division 1 Groups E, F, G; Class III for US and Canada. Complies with UL 913 and CSA C22.2 No. 153) and are suitable for a variety of critical flow measurement applications in the oil and gas and petrochemical industries.
Suitable applications include secondary oil recovery, remediation and reclamation, fracture/refracture, coal bed methane, regulatory compliance and environmental accountability, aggressive chemical processing, and industrial batching and dispensing.
