Description

Micronics MantaRay Portable Area-Velocity Flow Meter

Product Details:

The MantaRay is a portable area velocity meter designed for measuring flow using a submersible ultrasonic sensor. It’s ideal for conducting flow surveys in open channels, partially filled sewer pipes, and surcharged pipes, making it well-suited for applications like sewer monitoring, industrial flow analysis, irrigation systems, and natural streams.

Simple to Operate

The MantaRay measures both level and velocity to determine flow in open channels or pipes. Calibration is straightforward: just enter the pipe diameter or channel dimensions, and the meter automatically calculates and displays the flow rate and total on its backlit LCD.

The ultrasonic sensor is easily mounted inside the pipe or on the channel floor with a stainless-steel bracket (included) using a single screw. No special tools or compounds are needed. The sensor is fully sealed with no openings, preventing build-up and fouling.

Extended Battery Life with Sleep Mode

The MantaRay’s sleep mode conserves battery life by deactivating the display, outputs, and non-essential functions. The sensor briefly activates to take measurements based on the set logger interval, then returns to low power mode until the next reading. While in sleep mode, the display flashes periodically to indicate its status.

Flexible Power Options

For extended operations, you can connect external 12V or 24V DC batteries, or use the supplied charger for continuous power, long-term 4-20mA output, and relay functions.

Portable and Versatile Flow Monitoring

With its portability, the MantaRay is ideal for tasks like flow verification, sewer monitoring, industrial effluent studies, stormwater management, streamflow measurements, and irrigation.

Seamless Integration with SignalFire RANGER for Cloud-Based Reporting

When paired with the SignalFire RANGER, the MantaRay can operate in a power-saving sleep mode and “wake up” when the RANGER activates to transmit data to the cloud. This combination offers real-time insights into wastewater, environmental, or irrigation applications in partially filled pipes or channels.

⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.
