Description

Isobregeivov related to measuring equipment.

It is known a device for a 60tmvssy water meter, a hot water circuit with a freshwater circuit, a subsequent sequence is the same as the source of the Pregnant voltage with a frequency of 152 o kHz and a voltage regulator, to the output of which are connected. Electrodes, as well as a sensor, amplifier and self-voltage monitor, and the output of which are connected. This device has low accuracy.

With the accuracy of the proposed device in the proposed device, the sensor is filled in with a toroidal transformer, placed in a pipe of ferromagnetic material with an insulating coating. {by the uty, on whose coils there are installed electrically conductive materials, while the electrodes are fixed on the loose ends of the sockets, and the ends of the windings of the toroidal transformer are connected to the recorder through the series-connected amplifier and the additionally inserted straightener.

FIG. 1 shows a block diagram of the device; in fig. 2 is a time diagram of the voltage that measures the operation of the device.

The device for counting the biomass passing through Esanal 1 with fresh water contains series-connected alternating voltage source 2 at a frequency of 15-2 kHz and voltage regulator 3, to the output of which electrodes 4 are connected, as well as amplifier 5, recorder 6 and a sensor made in the form of a toroidal transformer 7, placed inside the pipe 8 of ferromagnetic material with an insulating cover, at the ends of which are mounted the sockets 9 of non-conductive material, while the electrodes 4 are fixed on the free end ah sockets 9 and concentrations gical toroidal transformer windings 7 via series connected amplifier 5 and 1O vtr DC converter connected to samopEstsu 6.

The device works as follows. 3628 Beams 9 send water and biomass to the transformer window 7. In the absence of biomass, a current U flows through the window of the transformer 7, the value of which is determined by the voltage at the output of the stabilizer 3 and the resistance of the circuit with the electrodes 4 at the input of the recorder 6 6 draws a plot of OT curves, (FIG. 2). During the passage of the biomass through the window of the transformer 7, the resistance of the circuit with the electrodes 4 is measured because the electrical conductivity of the biomass differs from the conductivity of water; mt y and a voltage of 11 increases (reduced) ,. and the recorder 6 draws a portion of the curve (shown in Fig. 2 for the case of an increase in voltage and). A pseudo of the biomass from, the windows of the transformer 7 is restored from the original current to the voltage 1G, and the plane 6 draws a plot of the curve Tg Tj. The amount of omvssa passed for the battery Tjf - Tj of the charbe of the transformer 7, О1ц is measured by increment of the bounded cusping curve U and the time axis compared with the adjacent sections of tf equal to: duration. For this purpose, pre-calibration devices are manufactured. When calculating fish of the same weight, (volume), the quality of biomass is divided into weight (volume) of one.

1. USSR author's certificate No. 122992, cl. A O1 C 61 / OO, 1972. Transformer 7 does not affect the current 3 The temperature of the water affects the circuit with electrodes 4 and the current 3, but this effect leads to a change in the level of H sp. TlTd, this level changes slowly, and the signal from the biomass is at the same level, so that the signal from BE | omass can always be distinguished from the head of the water temperature. The device provides high accuracy of counting the biomass passing through channel 1 forcibly or spontaneously. It will allow measurement of the fluid that is transportable with water in channel 1 or pipe.
