FIELD: oil and gas industry.
SUBSTANCE: dynamograph is installed on the pump jack and contains connected in series force measuring transmitter and amplifier connected to the first input of the controller, to the second input of the controller the movement transmitter is connected, and the radio unit connected with the third input of the controller. Additionally the power voltage generator is installed, to it the reception HF coil is connected. On the pump jack base the HF oscillations generator and transmitting HF coil are installed with possibility of transmission of the generated HF oscillations to the receiving HF coil.
EFFECT: use of wireless dynamograph to monitor operation of the well production pumps ensures refusal from use of the connecting wires, batteries, solar panels thus increasing reliability, ensures practically unlimited continuous operation life, high operation characteristics.
