Sensor of drilling mud flow rate DRU
.
The DRO sensor is designed to measure the flow of drilling fluids or liquids of different viscosity, which contain solid particles / gas bubbles (larger than 100 μm), in the pipe at the inlet to the well.
Sensor of drilling mud flow rate at the outlet, made on the basis of the invoice contactless sensor SE-4 and the controller DFM-5. The controller DFM-5 is installed in the heating room, the overhead sensor SE-4 - on the high pressure pipe (manifold).
The principle of action is as follows: the ultrasonic signal from the transmitter part of the overhead sensor enters through the wall of the pipe into a moving fluid flow. Reflecting on solid particles or air bubbles, the signal returns to the receiver of the sensor. Frequencies of signals transmitted and received for moving fluids are different (Doppler effect). The meter controller measures the frequency shift and calculates the flow velocity values of the fluid.

Sensor flow rate of drilling mud induction-magnetic RIM-10 0
.
RIM-100 induction-magnetic drilling mud sensor is designed to control the instantaneous flow of electrically conductive liquids and is installed in a pressure pipeline of a drill or tampon manifold.
In contrast to the existing analogs, RIM-100 compensates for the effect not only on the electrical characteristics but also on the magnetic properties of the liquid (when working on loaded drilling fluids), and, moreover, it is designed to work at high voltages of the power supply parameters (when operating from a diesel generator installation).
The principle of the induction flow meter is based on the law of electromagnetic induction, which makes it the only acceptable method for measuring the cost of cement and drilling fluids with high accuracy.

Indicator of drilling mud losses at IP output
M
.
The indicator of losses of drilling mud at the outlet of the IWM is intended to estimate the value of its flow in an open or closed chute.
The indicator of losses of drilling mud at the output of the IWM is established using a special bracket. For mounting on a trough a closed type in the mounting kit includes a box with a lid.
The design of the mounting kit allows you to quickly perform assembly-disassembly of the sensor.
The contactless type converter provides high reliability, durability of the sensor and reduces the time spent on its maintenance.
The principle of the IRM mud flow rate indicator is that under the action of the flow of the drilling fluid, the sensor's working blade is deflected, forming a magnet rotation relative to the magnetoresistive bridge. A normalizing amplifier generates an input signal value to a standard range.
The IRM indicator consists of a magnetoresistive converter of angular displacements and a normalizing amplifier, assembled in one housing.
