Product Specifications

Accuracy	1.0 % FS
Accuracy	Commonly ±0.2% FS or ±0.5% FS; some premium sensors can go to ±0.1% or even better.  Example: SMR02: ±0.1% (optional), ±0.05% FS for some materials.
Cable length	10 m
Communications / Interface	Some have analog only (4–20 mA), others have digital (RS-485 / Modbus) for remote calibration / diagnostics.
Enclosure rating	IP67
Insulation Resistance	Very high, e.g., > 100 MΩ at 250 V DC in some designs.
Long-Term Stability	e.g., ±2% FS per year for some designs.
Long-Term Stability / Drift	Depends on model; e.g., some: < 0.2% FS / year.
Measuring range	0 to 20 m
Measuring Range	From 0–0.5 m H2O up to 0–300 m H2O (varies by model)

Output signal	4 to 20 mA
Output Signal	Many support: 4–20 mA, 0–5 V, 1–5 V, 0–10 V, RS-485 (Modbus)Example: SMR02 uses RS-485 Modbus RTU.
Overload / Overpressure	Often rated up to 200% of full scale in many designs.
Parameter	Measuring range
Power Supply	Typical: 12–36 VDC, often 24 V DC.
Pressure Diaphragm / Wetted Material	Usually stainless steel (e.g., 316L); other variants may use more corrosion-resistant materials depending on range and medium.
Process connection	1 2 inch BSP
Protection / Ingress	Often IP68 on probe to be submersible.

Product Details

Hydrostatic level transmitters measure liquid level (depth) by measuring the pressure exerted by the fluid column above the sensor (hydrostatic pressure). The pressure is converted to a level reading, assuming known fluid density. Here are common technical parameters and their typical values: ParameterTypical Range / Specification Measuring Range From 0–0.5 m H₂O up to 0–300 m H₂O (varies by model) Accuracy Commonly ±0.2% FS or ±0.5% FS; some premium sensors can go to ±0.1% or even better.
