Abstract
The utility model relates to an ultrasonic calorimeter, comprising a temperature sensor, an integraph, and an ultrasonic flow sensor; the ultrasonic flow sensor comprises an ultrasonic transducer, a flow guiding frame, a measuring tube and an end; the measuring tube is hollow and dumbbell shaped; the ultrasonic transducer and the flow guiding frame are equipped from inner to outer in the inward spacing at two ends of the measuring tube; the end is fixedly joint with the end surface of the measuring tube; the conductor wire of the ultrasonic transducer is connected with the I/O interface of the integraph. This structural design makes the calorimeter have long service life not blocked by the contamination in water; measuring accuracy is increased, and performance is reliable.
Description
Technical field:
It is the gauge of central heating that the utility model relates to a kind of being used for the aqueous medium, and in particular, it relates to a kind of being used for the aqueous medium is the ultrasonic calorimeter of central heating.
Background technology:
At present, the heat metering device of heating is the important tool that promotes China's heating charging system reform, and prior art adopts the rotary wind type hot water gauge as the flow marker mostly, because water quality is relatively poor in the hot water system, impurity in the water often causes the rotary wind type hot water gauge to stop up, thereby can't work normally.
Summary of the invention:
The purpose of this utility model provides a kind of ultrasonic calorimeter, to remedy the deficiencies in the prior art.
The ultrasonic calorimeter that the utility model relates to, it includes temperature sensor, integraph, ultrasonic flow sensor, described ultrasonic flow sensor is made up of ultrasonic transducer, water conservancy diversion frame, measuring tube and termination, described measuring tube is hollow dumbbell shaped, in the space of measuring tube inward at both ends, be provided with ultrasonic transducer from inside to outside successively, the water conservancy diversion frame, fixedly connected with the end face of measuring tube in described termination; The lead of described ultrasonic transducer is connected with the I/O interface of integraph.
The guide face of described water conservancy diversion frame is the curved surface that outwards protrudes.
Described measuring tube and pipeline are on same axial line.
Described temperature sensor by on the water inlet pipe that is separately positioned on a heating unit and return pipe on two platinum resistance form, its lead is connected with the A/D interface of integraph.
During the work of the utility model ultrasonic calorimeter, hot water is by 2 ultrasonic transducers of ultrasonic flow sensor, 2 water conservancy diversion framves and measuring tube, the ultrasonic transducer that is provided with in the water intake end of measuring tube produces and the emission ultrasound wave along water (flow) direction, the ultrasonic transducer that is provided with in the water side of measuring tube then produces and the emission ultrasound wave along the opposite direction of current, two ultrasonic transducers receive the ultrasonic signal that the other side launches mutually, and convert thereof into electric signal, deliver in the integraph by lead and to handle, according to ultrasound wave in the flowing of fluid, the difference of the time that time that following current is propagated and adverse current are propagated and the flow velocity of detected fluid relation, obtain the flow velocity of hot water, make the hot water of the measuring tube of flowing through be in the Laminar Flow state by the water conservancy diversion frame that is arranged on the ultrasonic transducer outside, be convenient to the emission and the acceptance of ultrasonic transducer, make measurement result more accurate.Hot water induces return water temperature by the platinum resistance that the platinum resistance on the water inlet pipe induces on inflow temperature and the rising pipe, be input in the integraph, after treatment, the data archiving unit of data storing in integraph, and can show its data by counter or LED.
The advantage of the ultrasonic calorimeter that the utility model relates to is: by this structural design, make calorimeter not be subjected to that dirt stops up in the water, long service life has improved measuring accuracy, dependable performance.
