Flow Monitoring Products

MACE water flow monitoring equipment is designed to give you field-ready durability with accurate results you can trust. Whether you need to measure water flow, total volume, or level and velocity in open channels or closed pipes for industrial, wastewater, agriculture, and environmental markets, we’ve got your water flow testing needs covered.

Flow Monitoring Systems

The unique MACE XCi smart monitoring systems provide flexible and expandable site monitoring housed in rugged lockable enclosures. Battery, solar panels, and multiple card interface enable the user to control and log multiple sensors remotely from a single XCi device.

AgriFlo XCi

Monitors inputs as diverse as irrigation flows, farm wastewater flows, water quality, dam levels, soil moisture, and pump/engine management systems.

HydroMace XCi

Monitors inputs ranging from flumes and weirs, water quality sensors and rainfall gauges, drinking water flows (leak detection), and weather stations.


Advanced spectrum signal processing produces superior results under a wide range of hydraulic operating conditions.

Flow Sensors

MACE Doppler ultrasonic sensors for XCi devices transmit an ultrasonic (sound) wave into the flow. This sound wave is reflected by acoustically reflective particles (e.g. air bubbles, suspended solids), and the instrument detects these reflected frequencies. The difference between the transmitted frequency and the received frequencies is directly proportional to the velocity of the stream flow.

Doppler Ultrasonic Velocity Sensor

Measures velocity in full pipes when access to the pipe is available and the pipe can be emptied when installation/maintenance is required.

Doppler Ultrasonic Area/Velocity Sensor

Measures depth (using a capacitive pressure diaphragm) and velocity. Access to the monitoring point is required for installation and maintenance.

EchoFlo Ultrasonic Depth Sensor

Features patented Digital Signal Processor (DSP) technology that allows level measurement in a limited space.
