PUTF 205 ULTRASONIC WATER/HEAT FLOW METER
To work on measurements and for our needs, we researched and procured an ultrasonic flow meter PUTF 205 from the Chinese measuring equipment manufacturer Panda Machinery (Group) Co., Ltd.
Panda Machinery (Group) Co., Ltd is a high-tech enterprise established in 1993 and located in Shanghai, China. The company is located on an area of 200,000 m², and during its 29 years of operation, it has won many national awards and exports 258 of its products to more than 60 countries on five continents.
In addition to development, Panda Machinery (Group) Co., Ltd is one of the leading companies engaged in the research, production of pumps, water meters, flow meters, intelligent management platform consisting of raw water monitoring, water supply control, DMA, pipe GIS, secondary water supply and billing. It also has a certified laboratory for calibration of measuring equipment, and each product is supplied with a calibration certificate.
From now on we offer this meter that we tested and which proved to be reliable and precise in operation, with a very simple way of working, excellent performance and for our market a very acceptable price compared to other manufacturers.
Ultrasonic water-heat flow meter is a new generation of the series PUTF 205 which uses the principle of transit time to measure the velocities of relatively pure liquids in full tubes.
This flow meter can be practically applied to a wide range of long-term measurements.
The protection class of an ultrasonic flow meter is IP66, and the transducer protection class is IP67.
The measurement is applicable to different types of liquids, as follows:
- ultra-pure liquids,
- sanitary water,
- chemicals,
- wastewater,
- used water,
- cooling water,
- river water, etc.
The ultrasonic meter has a screen that is a 4 × 16 character LCD with backlight, as well as control lights for memory, battery charging, battery charge-full and for operation control - power.
The primary purpose of this US flow meter is precise measurement in water supply systems with the possibility of direct serial connection of several such meters in the SCADA system via MODBUS-ROUT PROTOCOL - RS 485.
Model PUTF 205 of this flow meter is adapted for mobile field work as a portable device with an autonomous rechargeable Li-Ion battery, which satisfies continuous operation - measuring the instrument for about 50 hours, without recharging. The device has been modified so that an additional power supply of 12-36 V battery can be connected, which extends the time of continuous measurement. The batteries are recharged with 220V, simply by connecting the charger to the power source
In the flow meter menu, in addition to the selection of the type of pipe material on which the measurement is performed, the diameter of the pipeline and the wall thickness of the pipeline, you have the choice of MEASUREMENT INTERVAL ranging from 1 sec to 1 hour.
When logging in, the number of measurements can be selected - as a default parameter, where the device will stop storing data after fulfilling the request.
The maximum default data recording-logging interval is 99h and 59min. If you need a longer constant measurement interval with a constant power supply, you can program the meter by entering **:**:** in the login time. The device then LOGS DATA CONSTANTLY without interruption until only one condition is met, which is the maximum filling of the memory capacity.
In the SETUP of the flow meter, you can have an insight into daily flow value, which are stored on SD memory (micro SD memory card) with a capacity of 32 GB, as well as the total monthly and yearly the flow value and the total value of thermal energy which are stored in the internal memory of the instrument.
The memory capacity of 32 Gb meets the needs of continuous measurement for approx. 20 years in a record interval of every 1 min in Excel CSV format.
The device is very easy to operate and does not require special conditions, except for meeting the general technical conditions for precise measurement.
The following technical parameters are entered before the measurement:
- Unit of pipe outer diameter: mm
- Pipe thickness unit: mm
- Pipe material
- Pipe insulation parameters: thickness and type (opt. Speed of sound) - if it has insulating material
- Type of liquid
- Probe type
- Probe mounting mode
There are two different methods — probe placement modes: V method and Z method
- V-method should be a priority for pipe dimensions in the range of nominal diameter DN20-DN200.
- Z-method should be prioritized for pipe sizes DN200 – DN1000. It can also be used when the device in V mode is not working well.
TYPE OF PROBE FOR ULTRASONIC FLOW METER PUTF 205
Signal strength and signal quality (Q value) upstream and downstream of the probes are very important, in order to obtain long-term stable operation of the meter and the most accurate measurement data. Also, the high quality of the received signal on the probes reduces the consumption of batteries as well as the external power supply of 12V-36V (battery-accumulator).
The signal strength is represented by the numbers 00.0 ~ 99.9, 00.0 means no signal and 99.0 means maximum signal.
The flow meter can work correctly and precisely when the signal strength is > 60.00
