ACCURON® 7500 Cartridge Flow Meter
Full Pipe Measurement
Pipe Size Range 8 “ to 24”
Unique design - Fully filled open ended pipe suitable
304 Stainless Steel Cartridge
Includes Velocity Sensors (Single or dual path)
with IP66 Backlit LCD Digital display
Accuracy +/- 1 to 2% of actual flow
The Accuron 7500 Cartridge Meter is designed to accurately measure flow in fully-filled open ended conduits. Available in both single and dual path configurations, the Series 7500 provides accuracy readings of ±1-2% (actual rate), depending upon flow profile conditions. Dual Path chordal sensor configurations are recommended for applications not having the necessary straight upstream runs to produce a well developed velocity profile. Since the average velocity component for each acoustic path is utilized to establish flow, flowmeter accuracy is relatively independent of the hydraulic profile.
FULLY OPERATIONAL IN 30 MINUTES
Selection of this model guarantees accuracy and cost efficiency by providing the end user with a pre-engineered field ready system designed for "out of the box" installation. A single cartridge, pre-sized for its specific application, arrives at the job site as a fully integrated unit, requiring only 30 minutes for installation. Every component is factory precision aligned, calibrated and programmed in strict accordance to customer supplied operating specifications.
The Series 7500 Cartridge Meters are calibrated at the factory to the application parameters provided by the customer. On-site calibration of the system is usually never required.
INFORMATION DISPLAY
The Accuron utilizes a 160 x 128 graphical LED backlit display. The main screen can be programmed to display up to eight lines of meter information such as flow, level, velocity, time, date and relay alarms.The order of display line information is programmed to user preference. The backlit display may be programmed to be ON or OFF, or to remain OFF during a selected time interval. Display contrast is fully adjustable
DATA LOGGING
The Accuron has a built-in datalogger with eight distinct channels for logging flow and totals.The storage capacity for a single channel at 5 minute intervals is 113 days. Logger data may be visually accessed on the display of the meter in pre-programmed time intervals or retrieved through a laptop or optional modem installed within the enclosure of the meter.
Daily Averages: Daily summary allows viewing of the previous eight days.
This includes times, dates, averages, minimums, maximums and totals.
Logger Graph: In addition, a bar graph may be visually displayed on the Accuron.
The graph will display the stored logger data in pre-programmed time intervals.
Data Retrieval: Logger data can be collected by using a lapto
DATA ACQUISITION
Current Output: 4-20 mA. Isolated, 800 ohms maximum.
Relay Outputs: Three SPDT relays available for alarm conditions.
Serial Outputs: RS-232/485: With Modbus protocol.
Data Logging: Eight distinct channels are available.
Communication Protocols: Modbus® , Profibus® or DeviceNet®
SURCHARGE (FLOODED) FLOW MONITORING
OPTIONAL SM-15 SURCHARGE MONITOR
To allow for the monitoring of conditions that change from open channel flow to submerged flow (as experienced in sewers during a storm event or downstream blockage), an optional, maintenance-free, "above the flowstream" independent level sensor can be provided for all Cartridge Meters.
The Accuron SM-15 non-contact Surcharge Monitor provides for continuous measurement of accurate flow data during intermittent periods of surcharged conditions. When utilized in conjunction with the Accuron 7200/7400 Area-Velocity Cartridge Meters, the Surcharge Monitor (an independent ultrasonic level sensor mounted near the highest point of the manhole) will accurately ascertain the sewerage or storm water level that has accumulated above the crown of the incoming pipe. During this event, flow continues to be monitored by the transittime velocity sensors integrated within the Cartridge Meter.
Since the Accuron SM-15 is located above the flowstream and calculates level by non-contact ultrasonic means, the requirement for periodic cleaning of the sensor, as is the case with submerged pressure transducers, becomes a non-issue. Field operating personnel may now monitor flow through both dry and wet weather conditions without the need for repetitive manhole entry.
