Following the lines of work based on the optimization of water consumption, from Mapsens® we have developed a device for monitoring volumetric capacities in water storages. The approach of the device is based on pressure measurements by means of probes submerged in fluids for points of interest, obtaining from these values the height of the water sheet. Applied to any type of storage for water supplies such as, for example, irrigation ponds.

Irrigation ponds constitute and have constituted the basic pillar for the modernization of irrigation systems. In a water supply network for agricultural use, storage ponds play a crucial role in maintaining a constant level of variation in the demand for the liquid for the uses of the irrigation system. The importance is as much for their contribution to the distribution of the liquid as for the storage capacity that they have for a competent supply.

Reservoir supply

Water determines the productivity of all your crops. By planning and controlling the supply, it is possible to guarantee the availability of water resources to meet the demand of agricultural crops, which leads to the fulfillment of commercial commitments.

Irrigation pond

The device developed, SensAgro P-1, incorporates a pressure probe or pressure transducer that transforms a force per unit area into a voltage proportional to the pressure exerted. That is, with the ratio of the pressure exerted by the water at a point, the device measures the height of the available water.

Field implementation scheme

To analyze the consumption from irrigation ponds we need to know the level and volume of water displaced from the pond to the final distribution. Focusing on measurements of the height of the water sheet for volumetric calculations.

P-1 sensor placed in an irrigation pond

The features offered by the device are working pressure ranges from 0 to 100 PSI and working temperatures from 0 to 85ºC. The probe is made of stainless steel, ensuring robustness, sanitation and long life; it can work in fluids such as gas, compressed air, water, fuel or oil. Reading accuracies around 2% of measurement errors.

Considering the pressure values of the probe, the maximum height, distance between the surface and the pressure probe, for any application is approximately 70 meters.

Sensor probe with metal box for insertion into the pond

From Mapsens ® we analyze the information on the height of the available water reserves by combining them with the other measurements obtained by the field sensors.

Real-time data from a P-1 sensor in Mapsens® Agro

Measurements of field parameters are taken at a fixed period of 15 min, a time interval sufficient to collect enough data for a detailed analysis of the level of available water reserves.
