Water tower level and temperature
Level monitoring in bodies of water or level monitoring in water towers with integrated temperature recording. Reduces the installation effort, since recording and transmission of the level and temperature values take place using one device. Simple signal processing by means of two separate, interference-insensitive signal circuits.

Product Help
Accuracy
What is the accuracy of the LMP307T?
The accuracy of the LMP307T is <0.35-0.5% FS for level measurement and <1°C for temperature measurement.
For level, there is also an addition error for temperature changes of 0.75-1% FS over 0 to 70degC, and if not regularly calibrated, there is also a long term stability error to consider of <0.1% FS per year.
Pricing
What is the price of the LMP307T?
Due to many configurations, approvals and high integrity waterproofing, the pricing of the LMP307T is relatively high compared to cheaper alternatives, and is only suitable for industrial projects which require a high spec and reliability in a challenging remote and outdoor environment. The price also varies significantly depending on the options selected, and in particular the cable type and length can take up a large proportion of the cost. Use the quote request form below to select options required to receive the price for your application requirements.
Level and temperature signal type
How does the LMP307T provide a signal for both liquid level and temperature?
It has two separate output signals, one for pressure (level) and one for temperature. The pressure signal is a 4-20 mA analog signal that varies linearly with the level being measured over a factory configured range of pressures. The temperature signal is also a 4-20 mA analog signal, and varies linearly with the temperature being measured over a factory configured range of temperatures.
Lowest and highest measured temperature
What is the lowest and highest temperature the LMP307 T can measure?
The lowest is 0 degC, an the highest is 70degC. There are three possible standard temperature measurement ranges you can choose from to build at the factory:
- 0 to 30 degC
- 0 to 50 degC
- 0 to 70 degC
Lowest and highest level range
What is the smallest range of level you can measure with the LMP307T, and the largest?
The lowest range is 1 metre of water (~100 mbar/1.45 psi), the highest range is 250 metres of water (25 bar/363 psi).
