Industry pain points:
Chemical liquid media are diverse (solvents, oils, additives) and require corrosion resistance
Batch filling or batching processes require high repeatability pulse output
There may be explosion-proof requirements on site, requiring intrinsic safety or explosion-proof design

Scheme composition:
Liquid turbine flowmeter motherboard/switchable waist wheel (elliptical gear) mode motherboard
High frequency pulse output, compatible with batch controllers
Supports dual outputs of 4-20mA and RS485
Optional battery or 24V power supply

Value return:
High resolution pulse output, meeting precise batch control requirements
The same motherboard can be adapted to turbine or elliptical gear flow meters, with flexible switching
Corrosion resistant circuit board coating, suitable for chemical field environment
