Pulsar Measurement has the technology to manage open irrigation channels – providing some of the best meters tracking velocity flow and water movement in channels.
In the agricultural and farming industries, knowing water consumption is essential. On many occasions, the water comes from nearby sources and is moved to many locations. Many local authorities will require permits or compliance for abstraction from these sources, so having accurate and reliable flow measurements is crucial for businesses to provide this information.
With that in mind, Pulsar Measurement has a range of flow meters that allows operators to ensure they are using the right amount of water for their irrigation process. With the irrigation process, it’s crucial to have the proper flow to avoid endangering the plants. An accurate measurement also helps keep the process efficient and maintains the natural local water source.
AVFM 6.1 Area Velocity Flow Meter
The Area Velocity Flow Measurement method is the most common method of all flow measurements. The AVFM 6.1 Area Velocity Flow Meter uses a submersible ultrasonic sensor that measures the level and velocity of flowing liquid to calculate flow measurement in an open channel or pipe. The sensors are mounted at the bottom of a canal and are built to resist fouling, corrosion, and abrasion. The unit can be configured with the standard submerged velocity-level sensor or submerged velocity in combination with a separate non-contacting ultrasonic level sensor. The combination suits highly aerated fluids or liquids with high suspended solids concentrations.
The AVFM 6.1 can measure forward flow velocity up to 6 m/s and reverse flow up to 1.5 m/s. The electronics and software sample and average flow rates continuously provide stable readings. The submerged velocity/level sensor will measure flow in partially full and surcharged pipes with pressure up to 10 psi.
Configuration is simple for the device. Enter the pipe diameter or channel dimensions, and AVFM 6.1 automatically computes and displays flow volume. Users can configure the unit for installation in irregular or compound channel shapes by entering the channel width and multiple level points through its menu system. Channels of virtually any shape can be monitored with the user’s choice of measurement units.
MantaRay Portable Area Velocity Flow Meter
The MantaRay is a portable area velocity meter that measures flow using a submersible ultrasonic sensor. The unit is designed for flow surveys in open channels, partially full sewers, and surcharged pipes. That makes the portable, open-channel flow meter suitable for sewer monitoring, industrial flow monitoring, irrigation flow, and natural streams.
It measures level and velocity to calculate open channel or pipe flow. It is simple to calibrate the MantaRay by keying in the pipe diameter or channel dimensions. The device automatically computes and displays the flow rate and total on its backlit liquid crystal display (LCD).
The ultrasonic sensor mounts inside the pipe or on the bottom of a channel. No unique compounds, tools, or hardware are required. The sensor is sealed with no orifices or ports, making it resistant to build-up and fouling.
Stingray 2.0 Portable Level Velocity Logger
The Stingray 2.0 is a Portable Level-Velocity Logger with free logger software for calculating flow as an open channel meter. The design is compact, portable, and battery-powered, making it a suitable instrument for open-channel flow measurement. Using four standard Alkaline D-cell batteries to operate as a battery-powered data logger, the unit is a complete area velocity logger with an ultrasonic sensor that data logs level, velocity, and water temperature for flow monitoring through open channels, partially full sewer pipes and surcharged pipes.
The sensor is installed in the bottom of a pipe or channel and requires no calibration. Use the included logger software to set the logging interval and get real-time flow readings on a laptop or PC. The built-in LCD lets users check level and velocity rates, remaining battery life, and logger memory.
The Stingray 2.0 display can scroll through the level, velocity, and temperature readings. To help with battery life, the display will turn off automatically after 60 seconds to preserve the battery.
It is suitable for many open-channel flow monitoring applications like flow surveys and studies, I&I (Inflow and Infiltration) studies, CSO monitoring, stormwater runoff, irrigation water, and permit compliance. The submersible ultrasonic sensor continuously monitors the channel’s level and velocity with no calibration required. The Stingray 2.0 stores 130,000 data points, and users can download the data via USB. Users can view real-time level and velocity readings, the remaining logger and battery capacity, and set the logging interval.
This compact, portable battery-powered data logger is designed for flow measurement in applications without a flume or weir, especially stormwater, combined effluent, raw sewage, irrigation water, raw sewage, and streamflow.
