Help: Seeking recommendations for explosion-proof secondary instruments
Thread Content
Here’s the situation: I was preparing a solution for a client, and I included our explosion-proof turbine flowmeter in it. However, the flowmeter outputs NAMUR pulse signals, and this meter itself doesn’t have any display function. Now the client has told me that it’s possible to use a third-party display secondary meter, so I’m asking fellow professionals to recommend one. The requirements are as follows: 1. Installation on-site; 2. Input of NAMUR high-speed pulses, output in 4-20mA format; 3. Explosion-proof rating for Zone 2; 4. Installation on-site; 5. Domestic brand (as I don’t want to incur excessive costs); 6. With a display
It’s simple: the flow meter costs 450 yuan, and the explosion-proof box is around 400 yuan as well; together they cost no more than 1,000 yuan
Explosion-proof electrical enclosures together with flow integrators can provide a cost-effective solution. For measuring ordinary gases, an integrated mass flow meter should be used, as it can directly measure the flow rate under standard conditions, eliminating the need for pressure stabilization compensation or additional display functions.

Looking for recommended brands that can receive NAMUR pulses
A flow integrator can do this; just add an explosion-proof box
