Digital Water Flow Meter ZJSUS BT01 DN15

Description

Digital Water Flow Meter – ZJSUS-BT01-DN15 Wireless LCD

The ZJSUS-BT01-DN15 is a wireless pulse digital water flow meter built for accurate flow measurement from 10 to 150 litres per minute. Made from 304 stainless steel with a G1/2″ female-female BSP thread, it connects easily to garden pipes, irrigation lines, and industrial systems — showing both instant flow and total accumulated volume on a clear LCD screen.

Powered by standard AAA batteries (included), this meter needs no wiring or external power supply. It suits home gardens, farm irrigation, and light industrial water management anywhere in Pakistan.

Key Features

• Dual-Reading LCD Display – Shows instant flow rate AND total accumulated volume at the same time, so you always know how fast water is flowing and how much has passed through.
• Wide Flow Range – Measures from 10–150 L/min (1.32–26.42 GPM), covering everything from a garden drip line to a farm main supply pipe.
• ±5% Measurement Accuracy – Variable-area paddle wheel turbine sensor with ±0.5% repeatability gives reliable readings for irrigation scheduling and billing.
• 304 Stainless Steel Body – Corrosion-resistant and built for outdoor, humid, and mildly industrial environments. Works with clean water and general-purpose waste water.
• Battery Powered — No Wiring Needed – Runs on 2 × AAA 1.5V batteries (included). Operates at 2.3–3.3V, making it safe and easy to install anywhere.
• G1/2″ Female-Female BSP Thread – Standard thread size that fits most garden hose fittings, drip irrigation connectors, and industrial pipe adapters without special tools.
• High Pressure Rating – Handles up to 1.75 MPa (17.5 Bar) — suitable for mains water pressure in most Pakistani homes and farms.
• Multi-Unit Display – Switch between Litres (L), Gallons (GAL), Cubic Metres (M³), or Quarts (QTS) to match your preference or billing standard.
• Large Measurement Range – Single reading up to 99,999 and cumulative total up to 99,999,999, so it keeps counting accurately over long periods.
• K-Value Calibration – Built-in calibration lets you fine-tune accuracy to your specific pipe and flow conditions using a simple formula (see Calibration Guide below).
• OEM / ODM Support – Custom branding, modified specs, and bulk orders available. Contact us for tailored solutions.

Calibration Guide

• When to Calibrate – Use calibration when the meter reading does not match a known measured volume (e.g., a marked container).
• Formula – New K = Current K × (Meter Reading ÷ Actual Volume). Example: meter reads 55 L, actual is 50 L, current K = 1000 → New K = 1000 × (55 ÷ 50) = 1100.
• Enter Calibration Mode – Hold the SET button for 5 seconds until the K-value screen appears and a digit starts blinking.
• Change Digits – Press CLEAR to change the blinking digit. Press SET to move to the next digit. Enter your new K value.
• Save – Hold SET or wait 30 seconds. The new K value saves automatically.
• Reset Old Readings – After saving, press CLEAR to reset previous totals, then test again with a known volume to verify.
• Rule of Thumb – If the meter reads too HIGH, increase the K value. If it reads too LOW, decrease the K value.
• Works for All Units – One calibration applies whether you display in L, GAL, M³, or QTS.

Applications

• Home Garden Irrigation – Monitor water use in drip or sprinkler systems to avoid overwatering and reduce your water bill.
• Farm & Agricultural Irrigation – Track flow across field supply lines for efficient water scheduling in crops, orchards, and greenhouses.
• Residential Water Monitoring – Measure water consumption for individual apartments, rooms, or rented properties for fair billing.
• Industrial Process Water – Measure and record water flow in light manufacturing, cooling systems, and washdown lines.
• Water Tank Management – Know exactly how much water enters or leaves a storage tank to manage supply accurately.
• Aquaponics & Hydroponics – Control and log water flow rates precisely for plant growth systems where consistency matters.
• Swimming Pool & Fountain Systems – Monitor circulation pump output and water top-up volumes easily.
