Sewer Flow Monitor Product Description
The Global Sewer Flow Monitor is reliable and accurate for measuring and totalizing sanitary
sewer system flows for VCP pipe. The sewer flow meter measures water depth with the highly accurate Global Water
pressure transducer. The electronic circuitry instantly calculates and displays the sewer system’s
flow and total flow values for any depth-to-flow relationship in any engineering units. The sewer flow meter is easily set up in the
field using its unique four-button programming system.
Sewer System Flows
For any sewer system that is free flowing, there is a specific relationship between depth of water and
flow rate. Whenever a given depth occurs, there will always be the same flow. Therefore,
if the flow rate is known for each depth, a depth-to-flow relationship can be constructed. The
Sewer Flow Monitors are pre-programmed with depth-to-flow relationship tables. When the
user digitally selects the correct sewer pipe table, the Sewer Flow Monitor's LCD screen automatically
displays accurate flow rate measurements for the maximum diameter of the sewer pipe. This water
flow is averaged over time to display total flow.
The Sewer Flow Monitors do not require a primary device to measure sewer flows. The sewer flow
meter has been pre-programmed with a carefully selected group of common pipe sizes and slopes to meet
the needs of the majority of sewer systems. Please review the sewer flow tables to determine if your
sewer system is supported. Global Water can program the sewer flow meters with custom tables to
meet your sewer system's requirements.
Sewer Flow Depth Measurement
The Sewer Flow Monitors measure flow depth with the highly-accurate WL400 Water Level Sensor,
which is a fully submersible water level sensor constructed of stainless steel. The standard level
range is from 0 to 3' of water, which provides for accurate flow measurements even with a depth change as
small as a fraction of an inch. The pressure transducer is mounted on the bottom of the sewer pipe
pointed downstream. Global Water recommends the use of our sewer flow option for maximum
protection of the pressure transducer. The water level sensor has a 2-wire 4-20 mA signal, so the sewer
flow meter enclosure can be mounted several hundred feet away, if required. The sensor and sewer flow
meter can be connected with standard, twisted-pair signal wire.
Global Water also offers an ultrasonic water level sensor that allows the Sewer Flow Monitor to measure
semi-solid flows or flows that are not suitable for a standard submersible pressure transducer. Global
Water recommends that the ultrasonic sensor option only be used in areas where AC power is available. You
should strongly consider using a submersible pressure transducer for applications that are in areas without AC
power.
Sewer Flow Monitor Display and Outputs
The sewer flow monitor displays flow rate on a large 6-digit LCD screen. The totalized output is shown on a
second LCD display. The display reads in user-defined units of flow, including MGD, CFS, GPM,
m3s. The sewer flow monitor also produces an analog 4-20 mA output signal that is proportional
to flow. This can be used for chart recorders, dataloggers, or as an input to telemetry or process control
systems. In addition, the sewer flow rate meters have a flow-proportional output signal for triggering
water samplers.
Sewer Flow Monitor Digital Flow Computer
The Global Sewer Flow Monitor has powerful internal electronic circuitry that calculates and totalizes sanitary sewer
flow. The user chooses the desired engineering units and selects a VCP sanitary sewer pipe table from a list of
over 20 pre-defined pipe tables. It is not necessary to open the sewer flow meter's enclosure to program the
unit. All programming selections are made using the four front panel push buttons.
Sewer Flow Monitor Enclosure
The Sewer Flow Monitor's enclosure is made of weatherproof injection molded plastic. It is suitable for use in a wide
variety of environments. The enclosure can be wall-mounted and fitted with conduit for sensor and
power connections, if required.
