Application: Discharge throttling

Flow-oriented and pneumatically driven control systems for responsive and precise flow limitation of wastewater, raw wastewater and rainwater.

Drainage control for waste water with pneumatic drive
Robust, transparent, accurate, fast, low maintenance and reliable for wastewater, raw wastewater and rainwater.

IDM-based pneumatic outflow control

Precise drain throttle for heavily polluted waste water. The IDM flow measurement for full filling is the central element of the almost self-cleaning, remotely operated and highly precise pneumatic discharge control PNA. The reliable and never-tiring flap with pneumatic drive and the pinch valve react quickly to changing flows and conditions.
Road drainage shaft
Rainwater treatment at the wastewater treatment plant without overloading the combined sewer system

INKA road drainage system

The INKA-controlled road drainage system allows contaminated rainwater to be safely routed to the wastewater treatment plant, while uncontaminated rainwater is routed directly to the separate system/watercourse. The first rainwater that washes off the First-Flush is collected in a storage pipe under the road and retained until the combined sewer system has the hydraulic capacity to safely discharge the volumes to the wastewater treatment plant.
LDM partially filled waste water flow measurement
Highly Precise Ultrasonic transit-time difference flow measurement for wastewater, raw wastewater and rainwater

LDM partially filled Flow measurement

Highly precise flow value acquisition. The LDM is a calibrated measuring device for backflow-free flow measurement of waste water in open channels or free flowing lines. 10 flow velocity measuring sections distributed over the entire cross section provide most accurate flow values when the sensor is partially or fully filled. The level measurement is integrated in the device housing.
LDM-controlled pneumatic discharge control with, throttle with partially filled flow measurement
Flow measurement and discharge control for wastewater, raw wastewater and rainwater in partially and fully filled pipes.

LDM-based pneumatic discharge control

Most reliable waste water throttle and discharge control with accurate flow measurement for partial filling and dry installation. The fast, almost self-cleaning and remotely controllable pneumatically driven pinch valve is based on the LDM flow measurement integrated in the system and limits waste water, raw waste water and rainwater quantities to a value that can be set as required.
Pneumatic discharge control partially filled TFPNA as rainwater basin control in the sewer system
The reliable discharge control for wastewater and rainwater

Pneumatic discharge control partly filled TF-PNA

Precise and easy to maintain throttle system for stormwater tanks and wastewater structures. The fast, almost self-cleaning and remotely controllable butterfly valve with pneumatic actuator is based on the flow measurement integrated in the system and limits the flow to an arbitrarily adjustable quantity. As long as the maximum flow is not reached, the flap remains open, while the flow measurement system measures precisely even when partially filled.
Portable flow measurement for wastewater and external water
Temporary use of the proven MID for full filling to collect high-precision measurement data.

Portable flow measurement with MID

Waste water and external water flow measurement Measurements are performed with a high-precision, portable MID flowmeter mechanically protected by a plastic layer, which is normally installed in existing shafts and ducts without structural modifications. A bypass cushion completely seals the channel cross section and guides the entire water quantity completely through the measuring system.
Battery-supported damper operation in the event of a power failure - simply via UPS in the control cabinet!

STEBAdrive

Smallest electrical power, highest torque even with battery operation during mains failure. The Scheidegger damper drive with 24V DC power supply convinces with its ideal power transmission. A selection of adapter parts allows the actuator to be mounted on all commercially available damper makes. Available for all standard sizes from DN50 to DN1000.
