Product details
Product Overview:
SP-LDE seriesDN150 saltwater meter, Tangshan saltwater flowmeterThe electromagnetic flowmeter can not only meet the on-site display requirements, but also output 4-20mA current signals for recording, adjustment, and control purposes. The main components of the sensor are the measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing.
Product features:
High definition backlit LCD display, fully Chinese menu operation, easy to use, simple to operate, easy to learn and understand. It has digital communication signal outputs such as RS485, RS232, Hart, and Modbus.
There are no movable parts or flow blocking components inside the pipeline, and there is almost no additional pressure loss during measurement.
The measurement results are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc.
On site, the range can be modified online according to the actual needs of the user.
It has self checking and self judging functions, and provides sensor non-linear correction function without any reason.
Using SMD devices and surface mount technology, the circuit has high reliability.
Adopting a 16 bit embedded microprocessor, it has fast computing speed and high accuracy, programmable low-frequency rectangular wave excitation, and improves the stability of flow measurement.
All digital processing, strong anti-interference ability, reliable measurement, high accuracy, flow measurement range can reach 150:1
Ultra low EM1 switching power supply, suitable for a wide range of power supply voltage changes, with good EMC resistance performance.
Power outage protection, the calculation results of the flowmeter and the parameters set by the user will not disappear after power outage, and EEPROM can protect the set parameters and accumulated values
The converter and sensor have multiple protection registration and installation methods, with an IP68 rating suitable for submersible installation.
Selection of electrode materials for DN150 brine meter and Tangshan brine flowmeter：
|
material |
Corrosion Resistance |
|
316L |
For nitric acid, sulfuric acid at room temperature<5%, boiling phosphoric acid, alkaline solution; Under certain pressure, media such as sulfurous acid, seawater, and acetic acid have strong corrosion resistance. |
|
Hastelloy HB |
Resistant to all concentrations of non oxidizing acids, bases, and non chlorinated hydrochloric acids such as hydrochloric acid, sulfuric acid, hydrofluoric acid, and organic acids at boiling point. |
|
Hastelloy HC |
Resistant to oxidizing acids such as nitric acid, mixed acids, or mixtures of chromic acid and sulfuric acid, as well as oxidizing salts and seawater |
|
titanium |
It can withstand corrosion from organic acids, alkalis, etc., but is not resistant to corrosion from relatively pure reducing acids (sulfuric acid, hydrochloric acid). However, if the acid contains oxidants (such as nitric acid and media containing Fe and Cu ions), corrosion is greatly reduced. |
|
tantalum |
It has excellent corrosion resistance similar to glass, except for hydrofluoric acid and concentrated sulfuric acid, and can withstand corrosion from almost all chemical media (including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 175 ° C). It is not resistant to corrosion in alkali. |
