1. Overview:
The mag flow water meter consists of two main components: a transmitter and a sensor. It is capable of measuring all conductive liquids. The transmitter handles power supply, signal output, and display functions; it comes standard with Chinese and English display options, with Russian and Spanish available upon request. For the sensor, the liner and electrode materials are selected based on the properties of the liquid being measured, while the housing is available in carbon steel, SS304, or SS316.
The mag flow water meter manufactured by Henan Junyuan Automation Equipment Co., Ltd. is equipped with four electrodes-one positive, one negative, and two grounding electrodes-which significantly enhances operational stability. However, when installing the meter on non-conductive piping (such as PVC), the addition of grounding rings is still required to ensure measurement stability.

4. Magnetic flow meter sensor manufacturing process:
⇒Pipe cutting ⇒Welding inner and outer flanges ⇒ Installing the liner ⇒Installing electrodes and coils ⇒ Welding the housing ⇒ Painting
Our mag flow water meter features all-copper coils and offers protection ratings of IP65, IP67, or IP68.
5. RFQ:
Q1. Are you a manufacturer or a trader?
A1: We are a manufacturer based in Kaifeng, China, established in 2002. We specialize in the production and sales of various industrial flow meters and related instruments. You are welcome to visit us!
Q2. What products and services do you offer?
A2: We provide comprehensive flow meter solutions. Our product range includes various industrial flow meters, industrial ultrasonic water meters, differential pressure transmitters, pressure transmitters, and other instrumentation.
Q3. What are your packaging specifications?
A3: We select the most suitable and secure packaging based on the product's weight and the shipping method. For lightweight equipment (especially for small-diameter pipes or express shipping), we use cartons with foam padding. For large-diameter equipment (especially for sea freight), we use wooden crates.
Q4. What is your delivery time?
A4: We maintain a large inventory of raw materials and standard-configuration equipment. For standard models (orders of 50 units or fewer), production and calibration take approximately 2 working days after order confirmation. For non-standard models, production time varies based on quantity and specifications but typically takes 5 working days; please consult our sales representatives for specific details.
Q5. What is your minimum order quantity (MOQ)?
A5: Our minimum order quantity is 1 unit.
Q6. How do you ensure product quality?
A6: We have a comprehensive quality control system; all products undergo thorough inspections by our IQC (Incoming Quality Control) and OQC (Outgoing Quality Control) departments before shipment.
