Level Transmitters

APC 2000 ALW/L

Smart Hydrostatic Level Transmitter

The APC‑2000 ALW/L series are intelligent, two-wire, loop-powered transmitters with built-in display and HART® communication. Available in both pressure and hydrostatic (level) versions, they offer programmable ranges, zero shifts, and damping-ideal for flexible industrial measurement tasks.

• Sensing Principle: Hydrostatic level measurement
• Accuracy: ±0.16%
• Output: 4-20 mA
• Connection: thread or flange mounted sensor
• Material: st-steel

NRM

Non-Contact Radar Level Transmitter

The KOBOLD NRM is an advanced, two-wire, non-contact radar transmitter using 25 GHz pulsed microwave (K-band) technology to continuously measure liquid levels up to 23 m in open and closed vessels. It delivers precise readings regardless of changes in dielectric constant, pressure, temperature, or vapor presence

• Measuring range: up to 23 m
• Accuracy: ±3 mm
• Pmax: 25 bar
• Tmax: +180°C
• Material: st-steel; aluminium; PP; PTFE
• Output: 4 - 20 mA

MM

Float Transducer-Reed Chain

The KOBOLD MM is a continuous level sensor and transmitter designed for liquids, based on a magnetically coupled float moving along a guide tube, with a potentiometric output. It provides reliable level indication using just one moving part-the float.

• Measuring length: up to 6 m
• Accuracy: 0.5 %
• Pmax: 30 bar
• Tmax: 130°C
• Connection: flange DN 40 - DN 125
• Material: st-steel; PVC; PPH; PTFE

SGE-25

Hydrostatic Level Probe

The SGE‑25 is a robust, submersible hydrostatic pressure sensor designed for continuous liquid level measurement in deep tanks or wells. It determines level by measuring the hydrostatic pressure at the probe tip, which is directly proportional to fluid column height.

• Measuring range: up to 20 m H2O
• Accuracy: 0.2 %
• Connection: cable up to 25 m
• Material: Hastelloy; st-steel

NMT

Float Magnetostrictive

The KOBOLD NMT is a high-precision, float-controlled magnetostrictive level transmitter designed for continuous liquid level measurement. It combines a stainless steel guided-rod sensor and an integrated transmitter to convert float position into an accurate analog output.

• Measuring length: 300 - 4000 mm
• Accuracy: ±1 mm
• Pmax: PN10
• Tmax: 70°C
• Connection: G 2; 2" NPT
• Material: st-steel
• Output: 4 - 20 mA

NGM

Guided Radar Level Transmitter

The KOBOLD NGM is a compact guided-wave radar (TDR) level transmitter designed for continuous, non-contact measurement of liquids and light solids. This instrument excels in harsh process environments thanks to its advanced time-domain reflectometry technology and modular probe design.

• Measuring range: up to 20 m
• Accuracy: ±3 mm
• Pressure range: -1 to +40 bar
• Temperature range: -50 to +250°C
• Connection: DN 40 - DN 100
• Output: 4 - 20 mA
• Material: st-steel

NUS

Ultrasonic Level

The KOBOLD NUS is a non-contact ultrasonic level transmitter designed for continuous measurement of liquid levels in tanks or flow in open channels. It emits ultrasonic pulses and measures the echo return time to determine distance accurately

• Measuring range: up to 25 m
• Connection: flange DN 80; DN 125; DN 150
• Pmax: 3 bar
• Tmax: 90°C
• Accuracy: ±0.2 %
• Material: polypropylene
