Insertion electromagnetic flow meter；ultrasonic flow meter with data logging, flow meter with 4-20mA output, battery operated flow meter

1. Product Overview
◆ Range: 0~180 Nm/s (standard condition: 0℃, 11.33 KPa)
◆ Accuracy: 1%, range ratio 100:1
◆ Operating temperature: -40~400℃ Quick-response dual armored sensor
◆ Corrosion-resistant performance sensor, suitable for measuring corrosive gases
◆ Expert algorithm for the full range, ensuring the accuracy of measurement The insertion gas mass flow meter is calibrated using a standard precision wind tunnel, adopting the principle of constant temperature and the thermal dissipation (cooling) effect of the Gold. It can display flow velocity (flow rate) and temperature simultaneously. It is sensitive to low flow rates and can also achieve good precision at high flow rates. It can achieve a constant temperature difference even at high temperatures, and it has good stability. 2. Product

Application
It can measure a variety of gases, directly output mass flow, and does require temperature and pressure compensation. There are two ways of explosion-proof and intrinsically safe, and two output options are available. It is suitable for measuring large bore, small, and a variety of installation options are available. Measured medium: air, natural gas, biogas, coal gas, dry chlorine, oxygen, flammable, flue gas, torch gas, hydrogen, argon and other dry gases.
