Product Overview:

SP-LDE series circulating water pipeline flowmeter, air conditioning return flow meterIt is an electromagnetic induction flow meter that works based on Faraday's law of electromagnetic induction. It consists of sensors and intelligent signal converters. It can measure the volumetric flow rate of various conductive liquids, including highly corrosive liquids such as acids, alkalis, salts, pulp, slurry, wastewater, seawater, and solid-liquid two-phase liquids. This product is mainly used in industries such as petrochemicals, steel, electricity, metallurgy, textiles, food, pharmaceuticals, papermaking, as well as in municipal environmental protection, water conservancy, and other fields.

Product Category:

The series consists of sensors and intelligent signal converters, which can be divided into two types of structures based on the assembly form of the converter and sensor: integrated and split.

Integrated: The converter and sensor are directly assembled as a whole and cannot be separated. Commonly used in sites with good environmental conditions.

Split type: The converter is composed of a dedicated cable and a sensor to form a product, with the sensor installed on site and the converter installed in a location with better conditions. Commonly used in sites with poor environmental conditions, such as underground wells, high temperatures, and places that are difficult for personnel to reach.
Selection of lining materials for circulating water pipeline flow meter and air conditioning return flow meter:

Lining material	Performance	Maximum medium temperature		scope of application
Lining material	Performance	All-In-One	separated	scope of application
PTFE （F4）	1. It is the most stable plastic that can withstand boiling hydrochloric acid, sulfuric acid, nitric acid, and aqua regia, as well as concentrated alkali and various solvents. 2. The wear resistance is not as good as polyurethane rubber. 3. Its ability to resist negative pressure is not as good as that of chloroprene rubber.	70℃	100℃ 150 ℃ (required) Special Orders	1. Corrosive media such as concentrated acid and alkali 2. Sanitary media
Perfluoroethylene propylene diene (F46)		70℃	ditto
Polyfluoroethylene （Fs）	The upper limit of applicable temperature is higher than that of polytetrafluoroethylene Ethylene is low, but the cost is also relatively low.	70℃	80℃
neoprene	1. Has excellent elasticity, high tensile strength, and good wear resistance. 2. Resistant to corrosion in general low concentration acid, alkali, and salt media, but not resistant to corrosion in oxidizing media.		80℃ 120 ℃ (special requirement) Special order)	Water, sewage, and weakly abrasive slurry
polyurethane	1. Extremely strong wear resistance 2. Poor corrosion resistance		80℃	Neutral strong abrasion slurry, coal slurry, mud
