DESCRIPTION

Model M17 open flow meters are designed to measure the flow in canal outlets, discharge and inlet pipes, irrigation turnouts, and other similar installations.
Model M17 meets or exceeds the American Water Works Association Standard C704-02.

FEATURES

Construction

Constructed of stainless steel, the meter incorporates bronze mounting brackets that permit simple installation and removal.

Impellers

Impellers are manufactured of high-impact plastic, designed to retain both shape and accuracy over the life of the meter.

Each impeller is individually calibrated at the factory to accommodate the use of standard McCrometer registers, and since no change gears are necessary, the M17 can be field-serviced without the need for factory recalibration.

Bearings

Factory lubricated, stainless steel bearings are used to support the impeller shaft.
The sealed bearing design limits the entry of materials and fluids into the bearing chamber providing maximum bearing protection.

Register

An instantaneous flow rate indicator is standard and available in gallons per minute, cubic feet per second, liters per second, and other units.
The register is driven by a flexible steel cable encased within a protective, self-lubricating vinyl liner.
The die-cast aluminum register housing protects both the register and cable drive system from moisture while allowing a clear reading of the flowrate indicator and totalizer.

Typical Applications

The McCrometer propeller meter is the most widely used flowmeter for municipal water and wastewater applications as well as agricultural and turf irrigation measurements.

Typical applications include:

Water and wastewater management
Canal laterals
Gravity turnouts from underground pipelines
Sprinkler irrigation systems
Golf course and park water management

INSTALLATION

Model M17 must be mounted on a headwall, standpipe, or other suitable structure so that the propeller is located in the center of the discharge or inlet pipe.

PIPE RUN REQUIREMENTS

A straight run of full pipe the length of ten pipe diameters upstream and one diameter downstream of the meter is recommended for meters without straightening vanes.
Meters with optional straightening vanes require at least five pipe diameters upstream of the meter.

REGISTERS

Mechanical Register

The instantaneous fl owrate indicator is standard and available in gallons per minute, cubic feet per second, liters per second, and other units.
The register is driven by a flexible steel cable encased within a protective vinyl liner. The register housing protects both the register and cable drive system from moisture while allowing a clear reading of the flow rate indicator and totalizer.

Digital Register

The optional FlowCom digital register displays a flowmeter’s flow rate and volumetric total. Available are four optional outputs: 4-20mA loop, open collector, optically isolated, and contact closure.
Unique units of measurement for rate, total, 4-20mA, and pulse outputs. The FlowCom can be fitted to any new or existing McCrometer propeller flowmeter. The FlowCom also features a built-in data logger.

Wireless Telemetry

The optional FlowConnect is designed specifically for wireless telemetry via either satellite or cellular data service. A manual meter reading is never required.
It uses either the mechanical register or the digital register (both shown above).

You can determine how often readings are made and transmitted to the cloud database, which you can view on a PC or a cell phone.
The viewing utility provides data tools that can analyze flow rate, consumption, and possible anomalies in an irrigation system.
