PRODUCT OVERVIEW

What is the Visum Small Grains?

The Visum Small Grains is a wireless blockage sensor that allows farmers/operators to remotely monitor the presence or absence of small grain and fertilizer flow in each row. When a flow interruption or blockage occurs, the operator is alerted immediately.

Available for both gravity-fed and positive-pressure systems, the sensor installs inline between the metering unit and the hose with no inter-row cables and no complex setup required.

A single system can monitor up to 99 rows simultaneously, detect fertilizer and small grain flow across the entire machine, using the Visum Monitor Kit.

COMPATIBLE EQUIPMENT

Machine Types

The Visum Small Grains is available in two versions one for each dosing system.

GRAVITY-FED

volume-based seed and fertilizer delivery

Designed to detect small seed and fertilizer flow in gravity-fed, volume-based systems. The sensor installs inline between the metering unit and the hose while maintaining the original hose length.

Detects flow/no-flow conditions on each row
Installed inline — no hose cuts needed
Maintain at least 15° inclination
Never install upside down

POSITIVE-PRESSURE

volume-based seed and fertilizer delivery

Designed to detect small seed flow in machines that use positive-pressure, volume-based delivery. Installation varies - avoid grouping sensors in the same area and maintain the minimum inclination.

Detects presence or absence of flow per row
Avoid grouping sensors in the same area
Maintain at least 15° inclination
Never install upside down

Frequently Asked Questions

Does the Visum Small Grains require battery replacement?

No. The Visum Small Grains has a long-life internal battery that does not require replacement during the normal lifespan of the product.

Can it monitor fertilizer and small grains at the same time?

Yes. The system allows simultaneous monitoring of fertilizer and small grain flow on the same machine and the same monitor — up to 99 rows total.

Is it compatible with gravity and positive pressure machines?

Yes. The Visum Small Grains is available for both gravity dosing and positive pressure dosing machines. Installation procedure may vary between the two types — refer to the product manual for details.

The monitor won't turn on. What should I check?

Check that the cable is intact and properly connected to a 12V–24V power supply (red/blue = positive, black = negative). Also verify that the fuse is plugged in and intact.

The monitor is beeping or showing alarms during normal planting. What could it be?

This is often caused by encrusted fertilizer on the sensor walls. Clean the inner surface with a soft cloth or sponge. Use running water and neutral soap for a more thorough cleaning — never use pressurized water, as it can damage the sensor.

The monitor has no sound. How do I fix it?

Access function F2 on the monitor and adjust the volume level. Volume can be set to mute (A1), low (A2), medium/factory default (A3), or high (A4).

The maneuver alert is triggering during active planting.Why?

Check that all rows have sufficient flow and that no section has been accidentally turned off. If the issue persists, inspect the sensors for fertilizer buildup on the walls and clean as needed.

How do I increase the brightness of the Visum monitor?

This is likely a configuration issue. Access function F3 and adjust the screen brightness. Available levels are: low (B1), medium/factory default (B2), and high (B3).

Several sensors are not communicating. What should I do?

The issue may be related to signal strength or antenna placement. Verify the antenna is mounted vertically on the monitor and has a direct line of sight to the sensors. Remove any radio interference sources nearby and reposition the monitor if needed.
