Flow Monitor
B3100 Series
DESCRIPTION
The B3100 Series flow monitor is a flexible, durable, easy-to-use
platform for your flow metering applications. Our trusted flow
metering technology now offers a new flow monitor with more
options and features than ever before with the B3100 Series.
APPLICATIONS
The B3100 monitor is suitable for application in a wide variety of
metering needs. A few of the more common industries are:
• Secondary oil recovery applications
• Remediation and reclamation
• Fracture/refracture
• Coal bed methane
• Regulatory compliance and environmental accountability
• Industrial chemicals
• Aggressive chemical processing applications
• Semiconductor manufacturing
• Fertilizer production and dispensing
• Pesticide manufacture
• Liquid batching and water cooling
FEATURES
• Explosion-proof according ATEX, IECEx, FM and CSA c-us
• Rugged 1 in. NPT thread for flow meter mounting
• Data logging to survey information
• USB communication for configuration using a
programming cable
• Modbus RS485 communication option.
• Easy configuration via PC with free downloadable software
• Easy K-factor and engineering unit configuration for
volumetric or mass readings
• Display shows flow rate, total, measuring units and a flow rate
indicating speedometer
• Seven-digit flow rate/total and 11-digit accumulated total
• Easy configuration with clear alphanumerical display
• Bright LED backlight
• Auto backup of settings and running totals
• Power requirements: Loop powered or battery
• Operational temperature – 40…158° F (– 40…70° C)
• Sixteen-point linearization of the flow curve,
with interpolation
• Field operation via through-the-glass keypad
