weir flow meter Factory Price

Kingmach positions itself in the mid-range of the instrument market — not the cheapest option, but a step up from no-name devices that arrive without a manual or calibration sheet. The weir flow meter uses a pressure-based level sensor to calculate flow over a V‑notch, rectangular, or trapezoidal weir. Since the sensor sits below the water surface, it handles foaming or floating debris much better than ultrasonic alternatives. The factory price includes factory calibration against a reference weir plate, but you can also ask for site-specific calibration if you provide the weir dimensions beforehand. Being a manufacturer with a broad geotechnical catalog means Kingmach can combine the flow meter with rain gauges, water level loggers, and GSM data transmitters in a single shipment — often with a volume discount. Custom requests like longer sensor cables, special range adjustments, or stainless steel housings for brackish water are welcome. The team also offers pre-sales sizing help: send them your expected flow range and channel shape, and they’ll recommend the right weir type and sensor span. After the sale, technical support continues via email or remote access, which matters when your site is a day’s drive from the nearest instrument shop. If your project timeline requires multiple monitoring points, Kingmach’s global distribution network can arrange consolidated shipping from their factory to your port, saving you logistics headaches. The bottom line is straightforward: you pay for a working measurement chain built around a weir plate, not for a sensor that needs another box to translate its signal. For anyone who has wrestled with incompatible components before, that completeness is worth noting.
