Suction lance with empty indicator for canisters, drums, and IBC containers
Media Extraction and Level Monitoring in a Single Solution
In many industrial applications, liquids must be safely dispensed from canisters, drums, or IBC containers. At the same time, it is crucial to reliably monitor the remaining liquid level to prevent production interruptions and dry running of metering pumps.
A suction lance with a built-in empty indicator combines both functions into a single system. It enables the safe removal of the fluid and provides early warning when the container is nearly empty.
Binsack Reedtechnik develops and manufactures suction lances with float switches for demanding industrial applications. Our solutions are used in a variety of sectors, including water treatment, the chemical industry, the food industry, building services engineering, and mechanical engineering.
What is a suction lance with an empty indicator?
A suction lance is used to safely and precisely remove liquids from containers. It is inserted into the container from above and connected to the metering pump.
A suction lance with an empty-tank indicator also has a built-in float switch. This switch continuously monitors the liquid level.
When a defined minimum fill level is reached, the sensor sends a signal to:
# PLCs
# Dosing systems
# Warning systems
# Alarm modules
# Process control systems
# Dosing systems
# Warning systems
# Alarm modules
# Process control systems
This allows for a timely response before the metering pump runs dry.
Why is a "no-show" notification important?
Many plants operate around the clock.
An empty chemical container is often not noticed until problems have already arisen.
An empty chemical container is often not noticed until problems have already arisen.
Typical consequences:
- Dosing failure
- Quality issues
- Production interruptions
- Pump damage
- Higher maintenance costs
- Unplanned service calls

- Production interruptions
- Pump damage
- Higher maintenance costs
- Unplanned service calls
Reporting an empty tank early on prevents these risks.
The operator receives a warning in a timely manner and can replace or refill the container.
Advantages of a suction lance with an integrated low-level indicator
Two Functions in One Assembly
Instead of installing separate components, media extraction and level monitoring are combined.
This reduces:
- assembly time
- installation costs
- assembly time
- installation costs
Dry-run protection
The built-in low-level alarm protects metering pumps from damage caused by running dry. This significantly extends the system's service life.
Space-saving design
Especially in compact systems, installation space is often limited.
Integrating multiple functions into a single assembly saves valuable space.
High operational reliability
Robust reed technology has proven itself in industrial applications for decades.
It is characterized by:
- High reliability
- Low maintenance requirements
- Long service life
How does a suction lance with float switch work?
Insert the suction lance into the container.
The metering pump continuously draws the fluid through the suction line.
At the same time, a built-in float monitors the liquid level.
If the level drops to the defined switching point, an electrical signal is triggered.
This signal can be used for:
- Alerts
- Alerts
- Alerting
- Container change
- Pump shutdown
- Automatic switchover to the reserve tank
Typical areas of application
Water Treatment
Water treatment plants use a wide variety of chemicals.
Examples:
- Sodium hypochlorite
- Hydrochloric acid
- Sodium hydroxide solution
- Flocculant
A reliable low-level alert ensures trouble-free operation.
Chemical Industry
Chemicals often need to be dispensed from canisters or drums.
Level monitoring significantly improves process reliability.
Swimming Pool Technology
For the dosage of:
- Chlorine
- pH adjusters
- Flocculants
Reliable tank monitoring is essential.
Food Industry
Cleaning and disinfecting agents are often dispensed using dosing systems.
Preventing stockouts helps avoid interruptions in critical processes.
Building Systems
Dosing pumps and chemical tanks are also used in the technical systems of buildings.

Suction lance with low-level indicator for OEM applications
Many customers integrate our systems directly into their own products.
Typical OEM sectors:
- Dosing system manufacturers
- Water treatment
- Mechanical Engineering
- Chemical plant construction
- Environmental Technology
We support OEM customers with:
- Development

Combination with dry-run protection
A suction lance with a low-level alarm is the ideal foundation for reliable dry-run protection.
As soon as the tank reaches a critical fill level, the system can:
- Trigger an alarm
- Inform the operator
- Stop the pump
- Activate the reserve tank
This helps prevent costly damage.
