A prepaid heat meter that can be installed separately

Abstract

The invention discloses a prepayment heat meter capable of being mounted in a split mode. The prepayment heat meter capable of being mounted in the split mode comprises a basic meter unit, an electronic unit, a reducer unit and a battery unit. The basic meter unit comprises a flow sensor, a temperature sensor pair and a control valve. The electronic unit comprises a calculator, and the reducer unit comprises a reducer. The electronic unit inputs signals from the flow sensor and the temperature sensor pair, and outputs the signals to the reducer unit. The battery unit supplies power for the electronic unit and the reducer unit. The reducer unit, the electronic unit and the battery unit are mounted in a reducer unit bin, an electronic unit bin and a battery unit bin respectively in a corresponding independent sealing mode. The reducer unit bin is fixedly connected to the basic meter unit, the output shaft of the reducer unit is connected with the valve element of the control valve, and the electronic unit bin and the battery unit bin are in detachable connection. According to the prepayment heat meter capable of being mounted in the split mode, the battery is convenient to replace, the prepayment heat meter capable of being mounted in the split mode can be suitable for different mounting environments and is convenient to maintain and read, and due to the fact that the reducer is provided with the independent sealing bin, maintenance is convenient to carry out.

Description

Technical field [0001] The invention relates to a heat meter, in particular to a prepaid heat meter that can be installed separately. Background technique [0002] At present, the heat meter is a meter used to measure and display the heat energy released or absorbed by the water flowing through the heat exchange system. It uses the physical quantities measured by the two sensors-the flow rate of the heat carrier and the temperature of the inlet and outlet, and then through the compensation and integral calculation of the density and enthalpy, the calorific value can be obtained. It is a mechatronic product based on a microprocessor and a high-precision sensor. Its working principle is: sensor Installed on the inlet and outlet pipes of the heat exchange loop respectively, and install the flow sensor on the inlet or outlet pipe; the flow sensor sends out the flow signal, the paired temperature sensor gives the inlet and outlet temperature signals, and the calculator collects the fl...

Problems solved by technology

This structure has the following disadvantages: since the electronic unit box is fixed on the base meter, it will be inconvenient to observe and read the meter if it is installed in pipes in different directions; when replacing the battery in the electronic unit box, the unit box must be opened to expose The main board can only be replaced, which is difficult to operate and there is a risk of damage; the reducer and the main board are in the same unit box, which is inconvenient for their respective maintenance, and once the base meter leaks, it will directly soak the main board and cause a short circuit, resulting in failure of the heat meter
