Hydrostatic Level Probe 4-20mA for Liquid Level Measurement

Hydrostatic Level Probe 4-20mA

This hydrostatic sensor is used for measuring the height of liquid in a range of 0-30m (based on cable length). The sensor is installed vertically at the bottom of the tank where the liquid level will be measured. It measures the hydrostatic pressure corresponding to the height of the liquid above the sensor. It can only be used in non-pressurized tanks. The measured liquid must have a viscosity similar to that of slightly turbid water.

• Suitable for measuring levels in water and water-based media; suitable for drinking water
• The level probe is installed at the bottom of the container
• A relative pressure sensing cell provides an accurate analog signal and good long-term stability
• Pressure compensation with surrounding pressure is achieved using a capillary with an integrated filter in the connecting cable to protect the tube from clogging
• Application area: Water, water-based media

Note: It is also essential to ensure that no debris settles at the bottom of the tank, preventing the liquid being measured from reaching the sensor.

This model does not have CE compliance, but it is reliable and highly accurate. It is suitable for home projects, DIY enthusiasts, farms, etc. For industrial applications, we can offer models with CE, explosion-proof, suitable for fuel, oil tanks, etc.
