The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed
of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.

The specific method of drilling: on the ground around the base of the flower and the drip line along the canopy, drill the vertical drilling rig with 4 to 5 holes with a diameter of 30 cm and a depth of 0.8 to 1 m, and then the leaves, thatch, Pig (bovine) manure, crop straw, etc. are filled into the holes. In order to prevent the mud from filling the hole when it rains, the hole can be covered with stones, and it is only necessary to remove the stone every time the fertilizer is applied.

Fluid temperature: -200°C~+200°C (higher temp. model is customizable)
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
The fertilization of flowers and trees mostly adopts the method of digging annular grooves or radial grooves. Such methods are not only time-consuming, but also have great damage to the roots of flowers and trees. In recent years, some flower farmers have applied fertilization methods on the ground around the base of flowers and trees, which is convenient, flexible, labor-saving and time-saving, and can greatly reduce the damage to the roots of flowers and trees. More importantly, fertilization by drilling method has less fertilizer loss and can make full use of a large amount of organic fertilizer in rural areas. Generally drilling once for sustainable fertilization for 2 to 3 years
